Ginny's at Grimmauld Place for the summer, where she's being babied and is sick of it. Draco's been shipped off to Snape so Narcissa can carry out "big plans," and winds up at number 12 (where he's being watched closely) for the summer, as well.

Ginny wakes up one morning and finds herself in a totally different world. The year is 1607, she's a Muggle, there are only few magical people in the world, she's an only child, she's betrothed to her worst enemy, and she's . . . a princess?!
