Extra normal
(Book)

"Charlie Greer is nothing special--at least not compared to her adopted siblings. Her younger sister is a ghost. Her brother Mateo is a werewolf. Gideon is the product of seriously sketchy experiments that gave him telekinetic powers. Even her parents work for the Division of Extranormal Investigations tracking down all things supernatural, alien, and otherwise unusual. Charlie's mom says her superpower is maturity--which doesn't really count. But what Charlie lacks in powers she makes up for by keeping the household running. Now, with her parents off on their first vacation in years, it's up to her to take care of her siblings and make sure nothing disrupts the trip. But then the new neighbors arrive. The Weavers are a nice, normal couple. Too nice and too normal. And for some reason, they don't seem to want Charlie to see inside their house. She's certain they're hiding something. Charlie has to uncover what's going on with the Weavers and stop their plans--without letting Mom and Dad find out anything is wrong" --,Publisher's description.
