The Lux Proofs by Laird Foster
The Field kids are freaks. Clerk is a sulfur burping thirteen-year-old convinced he comes from a volcano. Twelve-year-old Pazia knows she's a megafauna Morpher ready to morph. Ten-year-old Lucy changes color while Ed, her dorky twin brother, spits gooey blood after creepy dreams. And sure, they knew Amala (Grandma) was murdered seventeen years ago — but Ed’s latest dream reveals the mysterious murderer is on the loose! When a crate arrives from a parallel universe called Lux, their already weird life goes totally haywire. From Maine to Cousin Chuck's museum in New York City and bizarre places beyond, the kids encounter wacky strangers and shocking headlines. The unforgettable journey to find Amala's murderer before the killer strikes again has only just begun.
