Celebrate the 20th anniversary of the #1 New York Times bestselling Spiderwick Chronicles and get ready for the series soon to be streaming on Roku with this sixth installment in the fantastical adventures featuring updated text.

Eleven-year-old Nicholas Vargas already thinks his life has been turned upside down after his developer father remarries and moves his new wife and daughter into the soon-to-be completed Mangrove Hollow. But when an "expedition" to a nearby lake truns up a little nixie with a giant problem—the huge, lumbering, fire-breathing variety—it's suddenly up to Nick; his stepsister, Laurie; and his big brother, Julian, to figure out how to stop all of Florida from going up in smoke.
