Really like aspects of this. Trees are ancestors. Magic is intertwined with genetics and a post-apocalyptic earth and an advanced alien race. I like that this race is neither evil nor beneficent.

The magic is explained slightly. It seems like an iceberg though where we can see just the tip of a potentially massive magic system.

The action scenes drag on. There's a series of fights that don't push the plot forward or reveal any great extra depth. I feel like there is a better way to pass that time rather than detailing a series of nearly identical fights.

I think I'll buy the next book. I hope the slow aspects speed up. ( )
