Stand out books for me that I've read this year:

* The Tusks of Extinction by Ray Nayler (Short, but a great read)

* The Incandescent by Emily Tesh

* The Armchair Universe by A.K.Dewdney (First read this one many years ago, but I've been reading it again)

* Final Orbit by Chris Hadfield (third book in a series, so you'd want to start at the begining with The Apollo Murders)
