Description: A human diplomat kills his alien counterpart. Earth is on the verge of war with a vastly superior alien race. A lone man races against time and a host of enemies to find the one object that can save our planet and our people from alien enslavement... a sheep. 

Yes, you read that right. Welcome to The Android's Dream.

For Harry Creek, it's a nightmare. All he wants is to do his uncomplicated mid-level diplomatic job with Earth's State Department. But his skills and past training get him tapped to save the planet - and to protect pet store owner Robin Baker, whose own past holds the key to the whereabouts of that lost sheep. Doing both will take him from lava-strewn battlefields to alien halls of power. 

All in a day's work. Maybe it's time for a raise. (From the back cover)

Description: A final, apocalyptic, world war has killed millions, driving entire species into extinction and sending the majority of mankind off-planet. Those who remain, venerate all remaining examples of life, and owning an animal of your own is both a symbol of status and a necessity. For those who can't afford an authentic animal, companies build incredibly realistic simulacra: horses, birds, cats, sheep . . . even humans. (From Goodreads)

Description: In the year 2044, reality is an ugly place. The only time teenage Wade Watts really feels alive is when he's jacked into the virtual utopia known as the OASIS. Wade's devoted his life to studying the puzzles hidden within this world's digital confines--puzzles that are based on their creator's obsession with the pop culture of decades past and that promise massive power and fortune to whoever can unlock them.

But when Wade stumbles upon the first clue, he finds himself beset by players willing to kill to take this ultimate prize. The race is on, and if Wade's going to survive, he'll have to win--and confront the real world he's always been so desperate to escape. (From the back cover)
