Have you ever thought about what you would do if you only had 24 hrs left to live?  The Vanishing Deep by Astrid Scholte is a suspenseful dystopian Sci-fi thriller. This book is a tale based on two orphaned sisters in a futuristic water-world, Equinox and Palindromena. The oldest sister,  Elysea, drowns during a dive and leaves the younger sister Tempest to survive on her own. For two years Tempest was diving and saving money to resurrect her sister, Elyea. At Palindromena her sister is brought back to life for only 24hrs. Tempest wants to find out from her sister what happened the night she died and what were the secrets she withheld about their parents’ death. This Sci-fi thriller is a real page-turner and kept me thinking about what was going to happen next. I would recommend this book to anyone who enjoys a suspenseful thriller with a little bit of romance.
