Hilarious middle school adventure. This is billed as YA, but I've rarely come across titles targeted toward that younger demographic. Reads more like Middle Grade, plus a bit of kissing. Which is a great thing - it's fun, pacy, and confronts some challenging stuff without turning too dark.
Clever sciency mystery, shady cultish shadow organizations, a bunch of kids trying to figure out if they're going to be friends, enemies, or date. Great for boy readers as well, which is a good balance against all the uber-romancy paranormal and fantasy releases every year. Fits well alongside DJ MacHale's Pendragon series, but more of a light comedy feel, less tense thriller action. Some deeper stuff thematically, and meaningful statements and characterizations are applied in a way that doesn't interrupt the flow of story.
