A suspenseful sci-fi escapade plucks two children out of the ocean for a thrilling adventure.

Thirteen-year-old Aluna has lived her entire life under the ocean with the Coral Kampii in the City of Shifting Tides. But after centuries spent hidden from the Above World, her colony’s survival is at risk. The Kampii’s breathing necklaces are failing, but the elders are unwilling to venture above water to seek answers. Only headstrong Aluna and her friend Hoku are stubborn and bold enough to face the terrors of land to search for way to save their people. But can Aluna’s fierce determination and fighting skills and Hoku’s tech-savvy keep them safe? Set in a world where overcrowding has led humans to adapt — growing tails to live under the ocean or wings to live on mountains — here is a ride through a future where greed and cruelty have gone unchecked, but the loyalty of friends remains true.

        Above World was alright. It's about a girl named Aluna who lives in the ocean with all the other Kampii(which are pretty much mermaids) in the City of Shifting Tides. But when the tech that allow Kampii to breathe water begin to fail, it's up to Aluna and her friend Hoku, the only ones brave enough, to go above on land to find a solution, along with some other friends they make along the way. It was a little interesting and adventurous.

              A good book. It tells a story about a dystopian world in the future when people adapt to the skies, desert, sea, ocean and deep ocean when the Earth reaches human capacity.

                Aluna has lived her entire life under the sea. She is a Coral Kampii - a splinter of humans that came to live in the sea generations ago to escape the horrors and dangers of the above world. She is only a day away from getting her tail and being confined to the water forever when she sees her friend floating dead in the water. Her breathing shell - the shells attached to their throats that allow them to breathe under water - had broken, causing her to drown. When she reports it to the Elders, she is surprised at their obstinance: ‘no one will venture out to the Above World’, they say, ‘no one will go looking for HydroTek, the tech company that made the necklaces’, ‘these deaths were just accidents’. Aluna knows the survival of her fellow Kampii and the city are in danger so she rejects her tail and escapes above in a last effort to save her people (and escape the fate that they’ve laid out for her - who wants to stay at home safe all day so she can rear children? She wants to be a hunter!) But can Aluna and her tech-savvy best friend Hoku survive in a world full of dangerous no-longer-humans, modified to live in their extreme environments as a cause of overcrowding and save their city too? This is a dystopian novel set in a world so far in the future where overpopulation has led humans to adapt to live in harsher environments - growing tails, wings, horse hooves, etc. It’s a very engaging story and is very suspenseful, kind of scary, but very exciting. It teaches to think beyond the set boundaries and to think before you act. Loyalty and friendship were very evident themes and the technology was like a kind of magic. I think this is a great read that most kids should enjoy.

                  This is an intriguing book with an interesting setting. Set in a futuristic mess, the characters fight against the norms of their peoples. There is plenty of spirit and adventure, but the plot is slightly scattered, coming through in bits and pieces. All in all, a story that is a good book to spend a lazy summer afternoon reading.
