Grimm Legacy

Leo never imagined that time travel might really be possible, or that the objects in H. G. Wells' science fiction novels might actually exist. And when a miniature time machine appears in Leo's bedroom, he has no idea who the tiny, beautiful girl is riding it. But in the few moments before it vanishes, returning to wherever - and whenever - it came from, he recognizes the other tiny rider: himself!

Sukie's been lonely since the death of her big sister, Kitty - but Kitty's ghost is still with her. At first that was comforting, but now Kitty's terrifying anyone who gets too close. Things get even weirder when Sukie moves into her family's ancestral home and an older, less familiar ghost challenges her to find a treasure. Her classmate Cole is also experiencing apparitions. Fortunately an antique broom's at hand to fly Sukie and Cole to the New York Circulating Material Repository's spooky Poe Annex.
