Meet the Sinister-Winterbottoms: brave Theo, her timid twin, Alexander, and their older sister, Wil. They're stuck for the summer with their strange aunt Saffronia.

When their aunt suggests they visit the Fathoms of Fun Waterpark, they agree. But the park is even stranger than Aunt Saffronia. The waterslides look like gray gargoyle tongues. The employees wear creepy black dresses. And suspicious goo is seeping into the wave pool.

Something mysterious is happening, and it's up to the twins to get to the bottom of it. But are Theo and Alexander out of their depth?
