Book 1
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?

Book 2
The spooky summer adventures of the Sinister-Winterbottom twins continue in another gothic mystery: can Theo and Alexander solve the secret of the Sanguine Spa in the little Transylvania Mountains? The second book in the new Sinister Summer series by #1 NYT bestselling author Kiersten White, called "perfect for fans of Lemony Snicket, Edward Gorey, and Roald Dahl," by Shelf Awareness.
After leaving Fathoms of Fun, the kids are on their way to the next odd summer destination their aunt has chosen for them. This time, they find themselves dropped off at the Sanguine Spa in the “little Transylvania Mountains.” There they meet the owners: Mina, her mysterious little sister, Lucy (who is extremely pale, can’t go in the sunlight, and has an affinity for hanging upside down from the ceiling), and their intimidating guardian, the Count.
When the Count sends all the children in the spa on a scavenger hunt, the Sinister-Winterbottoms use the excuse to snoop around and discover that this spa may be more than just eerie—it might also hold clues to what happened to their parents. When Wil starts to show vampiric symptoms, the twins resolve to investigate what’s really going on at the Sanguine Spa.
The second book in the Sinister Summer series continues the adventures of the Sinister-Winterbottoms and their aunt who never saw a discount vacation destination she didn’t love.
