Dinosaur Wars: Earthfall
Dinosaurs - from - SPAAACE!If you need more of a review than that, this may not be the book for you, but...
Technologically advanced dinosaurs attack earth from their base on the moon. They manage to take out most communications and ground based military assets.
Groups that managed to escape the destruction attempt to counter the threat, meanwhile the dinos' have started to reintroduce other species across the land.
The characters can be a bit flat in places, and there's a fair amount of deus ex machina when main characters are about to have something nasty happen and manage to avoid it.
As a first book in a series, its not too bad to intoroduce characters. Plus this is currently free on Amazon (books 2 and 3 need to be paid for), so can give it a go to see if you like it.
