A middle-grade mystery series that's spooky, creepy, and filled with
gothic twists! 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.
"An absolute delight. If I have to die in a waterpark, I want to die in
this one."**--**Holly Black, #1 New York Times bestselling author of
The Cruel Prince
Wickedly weird. . . . Will appeal to anyone who loved A Series of
Unfortunate Events. **--**The New York Times
Meet the Sinister-Winterbottoms: brave Theo, her timid twin, Alexander,
and their older sister, Wil. They're stuck for the summer with their
Aunt Saffronia, who doesn't know how often children need to eat and
can't use a smartphone, and whose feet never quite seem to touch the
floor when she glides--er--walks.
When Aunt Saffronia suggests a week pass to the Fathoms of Fun
Waterpark, they hastily agree. But the park is even stranger than Aunt
Saffronia. The waterslides look like gray gargoyle tongues. The
employees wear creepy black dresses and deliver ominous messages. An
impossible figure is at the top of the slide tower, people are
disappearing, and suspicious goo is seeping into the wave pool.
Something mysterious is happening at Fathoms of Fun, and it's up to the
twins to get to the bottom of it. The mystery, that is. NOT the wave
pool. Definitely NOT the wave pool. But are Theo and Alexander out of
their depth?
