An emotional rollercoaster 5/5 The book follows Nathan and his 7-year-old daughter, Jessie, who are on board a ship going to the Galapagos Islands when suddenly the seawater starts to evaporate and they find themselves stranded on the bottom of the dried-out seabed. This survival-horror book follows their struggles as they try and make it to safety. Whilst the characters are lovable, the story is filled with challenges and dread and there is a ton of emotion in this book which makes you care for the characters. You'll want only the best outcome for them as they make their way through the dry wasteland and the ending will stay with you for a long time. Overall I loved the book, even the ending and its dark themes, and can highly recommend it for everyone.
