The Last Shadow Gate

Summer vacation was never supposed to be like this.

It was bad enough Naomi had to be shipped off to her dad's home for the summer and deal with her half-brother Gavin, but when the siblings are forced to spend their break with their great-grandmother in upstate New York, everything changes. An investigation into the strange disappearance of their great-grandfather forces them to retrace his footsteps. They discover a gateway between worlds and encounter extraordinary creatures in a land where the people are desperate to escape the coming of a shade lord. To survive their adventure, Naomi and Gavin must settle their differences and find the elusive shadow gate that will take them home again.
