Above and Below: Sea and Shore by Harriet Evans


A Stunning Split-View Journey into Marine and Coastal Life

Above and Below: Sea and Shore is a breathtakingly illustrated nonfiction picture book that invites young readers to explore the dynamic world where land meets ocean - not just from one angle, but from two. With every turn of the page, children are offered a dual perspective: what’s happening above the surface and what’s unfolding below it.

Harriet Evans’ text is both informative and lyrical, introducing children to diverse coastal environments and the rich ecosystems that thrive there. Each spread highlights a different habitat - from rocky cliffs to coral reefs - and gives equal attention to the creatures that inhabit the air, land, and sea. The concise yet engaging descriptions make this a perfect introduction for early elementary readers who are curious about nature and the interconnectedness of life.

What truly elevates the book is Hannah Bailey’s artwork. Her illustrations are intricate and immersive, combining scientific detail with soft, inviting color palettes. She masterfully captures the hidden beauty of tide pools, the motion of schools of fish, and the drama of sea birds in flight. The split-page layout adds a sense of wonder and discovery - almost like lifting a flap or peeking into a secret world.

This book does more than educate; it sparks a sense of curiosity and environmental awareness. It gently encourages young readers to look more closely at the natural world and consider the delicate balance between ecosystems. As a literacy educator, I also appreciate how it supports vocabulary development, reading comprehension, and visual literacy - especially when read aloud and discussed with an adult.

Above and Below: Sea and Shore is a valuable addition to any child’s bookshelf, classroom, or school library. It’s a celebration of marine and coastal biodiversity, beautifully told and beautifully shown - a perfect pairing of science and art.

A Tender Tale of Loss, Hope, and Finding One’s Song Again

Gerda. Historia wieloryba is a deeply touching and visually stunning picture book that follows the emotional journey of a young whale named Gerda, who loses her brother and sets out on a voyage across the ocean to find herself - and her voice - again.

As a language teacher and children’s book reviewer, I also appreciate how the lyrical text and rich vocabulary lend themselves to deeper discussion, emotional literacy, and even philosophical reflection. The Polish translation by Joanna Partyka preserves the poetic quality of the original, making this version accessible without losing the heart of the story.

Gerda. Historia wieloryba is a tender and timeless tale - one that stays with you like a quiet song in your heart. Ideal for families, educators, or anyone who values picture books that speak to both the heart and the imagination.

My rating: 5 of 5 stars

A gentle ocean tale with a glowing heart

Some stories shine with such a simple, joyful light that they immediately find a home in your heart. The Biggest and Brightest Star in the Sea is one of those rare treasures. It's a picture book that wraps meaningful lessons in ocean-blue hues, kindness, and charm.

Written by Chelsea Paulus and beautifully illustrated, this story introduces us to Bellamy, a little sea star with a big dream: to rise above the sea and become the North Star. But when his plan doesn’t go as expected, Bellamy begins to doubt his worth. That is, until he discovers a new way to shine and that is by helping others.

This underwater journey isn't just about finding purpose but rather about redefining what it means to matter. Bellamy's story gently nudges children toward important emotional insights: that self-worth isn't tied to size, status, or applause, but to the kindness we show and the help we give.

Vivid illustrations bring coral reefs, curious fish, and Bellamy himself to life in bright, dynamic scenes. Together with the gentle text they convey perfectly a message of self-esteem and empathy that feels just right for children ages 3 to 7.

This book fits seamlessly into any collection focused on emotional development, kindness, and resilience. It’s perfect for parents raising thoughtful humans, and for teachers looking to introduce social-emotional themes through storytelling. Engaging narration reads beautifully aloud which is ideal for bedtime or classroom discussions.

Whether your child is a dreamer like Bellamy or simply loves ocean tales, this book will remind them that they already have a light within them and sometimes, they just need a reason to let it shine.

A Rhyming Ocean Adventure with a Big-Hearted Message

The Whale Who Wanted More is a joyful and visually spectacular picture book that pairs Rachel Bright’s lively rhyming text with Jim Field’s bold, expressive illustrations to deliver a memorable tale about what really matters.

The story follows Humphrey, a curious and kind-hearted whale who is always searching for more - more shells, more shiny things, more treasures from the sea. He collects endlessly, piling up his possessions, hoping they will make him feel complete. But as his collection grows, so does his loneliness. It's only when he meets a friendly, free-spirited crab that Humphrey begins to understand that the greatest treasures in life aren’t things - they’re friendships, shared adventures, and being part of something bigger than yourself.

The rhythm carries the story along at a lively pace, while the message unfolds gently and organically - never preachy, but thoughtful and heartfelt. Jim Field’s illustrations are a feast for the eyes: rich colors, dynamic compositions, and humorous details bring Humphrey’s underwater world to life in full cinematic style.

This book offers plenty for young readers to enjoy - whether it’s the catchy rhymes, the emotional journey, or the delightful sea creatures on every page. It also opens the door to valuable conversations about materialism, mindfulness, gratitude, and connection.

As a language educator and picture book reviewer, I find The Whale Who Wanted More not only entertaining but deeply useful in classroom or bedtime settings. The rhythmic text supports phonological awareness, the vocabulary is expansive yet accessible, and the story encourages empathy and reflection - all key ingredients for building both language and emotional intelligence.

Bright, buoyant, and beautifully told, this is a treasure of a book with a heart as big as its hero.
