I Bring the Fire9 books in series
In the middle of America, Amy Lewis is on her way to her grandma's house. She's being chased by a very bad wolf. Galaxies away, Loki is waking up in a prison cell, strangely without a hangover and with no idea what he's done wrong - this time, anyway. But he does know that Thor is hiding something, Odin is up to something wicked, and there seems to be something that he's forgotten....
In this urban fantasy tale that is equal parts Dresden Files and American Gods, a very nice Midwestern girl and a jaded, mischievous Loki must join forces to outwit gods, elves, magic-sniffing cats, and nosy neighbors. If Loki can remember exactly what he's forgotten and Amy can convince him not to be too distracted by earthly gadgets, earthly pleasures, or three-day benders, they just might pull it off.
