From New York Times bestselling author Kiersten White comes her middle grade series debut! Part Scooby Doo, part A Series of Unfortunate Events, and entirely genius! Meet the Sinister-Winterbottom twins, who solve mysteries at increasingly bizarre summer vacation destinations in the hopes of being reunited with their parents—or at the very least finally finding a good churro.
Twelve-year-old twins Theodora and Alexander and their older sister Wilhelmina Sinister-Winterbottom don’t know how they ended up with their Aunt Saffronia for an entire summer. She’s not exactly well equipped to handle children. The twins are determined to make it a good vacation, though, so when Aunt Saffronia suggests a waterpark, they hastily agree.
But Fathoms of Fun is not your typical waterpark. Instead of cabanas, guests rent mausoleums. The waterslides are gray tongues extending from horrible gargoyle faces. The few people they encounter are very, very odd. And the owner disappeared under bizarre circumstances, lost to the Cold, Unknowable Sea—the wave pool.
When Wil goes missing, rule following, cautious Alexander and competitive, brave Theo will have to work together to solve the mystery of Fathoms of Fun. But are they out of their depth?
Kiersten White is the New York Times bestselling author of The Dark Descent of Elizabeth Frankenstein, the Slayer series, the And I Darken trilogy, and many more novels. She lives with her family near the ocean in San Diego, which, in spite of its perfection, spurs her to dream of faraway places and even further-away times.
Sinister Summer consists of four works, and the series is set to expand with the upcoming release of one more book. The current recommended reading order for the series is provided below.
