You really need to read this!
Humans have migrated from earth to another planet, in another solar system, where they lived and built cities, and then the worst happens – bad aliens chase good aliens through a rift in space, and they both crash land on our human planet. Good aliens continue to fight the bad aliens who are now decimating the human population.
And then… the good alien guys find that they are becoming attracted to the female humans. And the females are definitely becoming attracted to the good alien guys.
There are several books in this saga, and some of them are terrific, some of them are quite good, and some of them are just OK. But as a whole, this is a really worth listening to or reading. I highly recommend this saga.
