Heir to the Lamp - Genie Chronicles, #1

A family secret, a mysterious lamp, a dangerous Order with the mad desire to possess both. Ginn thinks she knows all there is to know about how she became adopted by parents whose number one priority is to embarrass her with public displays of affection, but that changes when a single wish starts a never-ending parade of weirdness marching through her door the day she turns thirteen. Gifted with a mysterious lamp and the missing pieces from her adoption story, Ginn tries to discover who.or what.she really is.
That should be strange enough, but to top it off Ginn's being hunted by the Order of the Grimoire, a secret society who'll stop at nothing to harness the power of a real genie. Ginn struggles to stay one step ahead of the Grimms with the help of Rashmere, Guardian of the lamp and the most loyal friend a girl never knew she had. The Grimms are being helped, too-but by whom? As much as she doesn't want to, Ginn's beginning to question the motives of her long-time crush Caleb Scott and his connection to her newest, most dangerous enemy.
