Thursday - War of the Waterslides: Ralph Lazar

Book four in the hilarious and action-packed Total Mayhem series from New York Times bestselling author Ralph Lazar, starring Dash Candoo, an ingenious problem-solver, with fantastic friends and a bottomless backpack of brilliant gadgets.
For Dash Candoo, every day is... wild!

Dash and his friends Rob and Greta are used to unusual things happening at their school, Swedhump Elementary. But even they pay attention when their invisible principal, Mrs. Rosebank, announces that they have a special guest: Ms. Aqualine, the owner of the new Aqualina Water Park.

Most elementary students don't get to spend time on waterslides during the school day. But soon Dash, Rob, and Greta are slipping and sliding... right into a mystery!

It turns out there's more to this water park than splishing and splashing. There's something very evil going on, and instead of soaking it up, Dash and his friends are going to catch a wave... and ride it to victory in the war of the waterslides.
