Ulysses Moore 11. El jardín de cenizas

Ulysses Moore has vanished. It looks as if he's on the trail after his wife, who disappeared twelve years ago. But, where did he go? Rick, Julia, Jason, Anna, and Tommy need to find him soon and suspect that he's gone through a time portal ... but it will take centuries to explore them all. Besides, they're not the only ones looking for the old traveller. An old enemy has returned, set on getting revenge.
