I Bring the Fire: the Loki Series by C. Gockel

Amy Lewis is on her way to her grandma's house, and she's being chased by a very bad wolf. Galaxies away, Loki, Norse God of Mischief and Chaos, is waking up in a prison cell with no idea what he's done wrong. This time, anyway. Their fates are about to collide, and they'll have to work together to defeat gods, elves, magic-sniffing cats, and nosy neighbors.
