Some of the greatest joys I've had as a writer have been the precious friendships with other writers. Christopher Hopper is a friend I got to know on both an east coast and a west coast book tour several years ago.
It's my delight to share that he has a new book out. 
Check it out here!
Here's his description of The Sky Riders:
An Inventors World Novel by Christopher Hopper
On the floating cities above the cloud-floor, the only rule is 
don’t fall.
Enter the avionic steampunk world of master storyteller Christopher 
Hopper as he takes readers on a fast-paced, death-defying adventure in 
the skies.
Junar is a seventeen-year-old boy following in the footsteps of his 
Ace Pilot father, Leif, as a flyer in the Kili-Boranna Guild, better 
known as 
The Sky Riders. As if life couldn’t get any better, 
Junar’s First Year apprenticeship riding the massive birds of the sky, 
the majestic felrell, takes a fortuitous leap forward when his father is
 promoted to the most prestigious position in all of Aria-Prime-Timber 
Pilot.
Upon moving to the capital city of Christiana with his family, 
Junar meets fellow apprentices Liv, a strong-headed and alluring 
confidant, and Erik, whose favorite pastime is making life miserable for
 Junar.
Junar’s world takes an unexpected turn, however, when his father has a
 startling change of heart about his promotion. Embarrassed by his 
father’s weakness and his mother’s past, Junar endeavors to excel in his
 apprenticeship, and distances himself from his family by making his own
 name in the Guild. He sets his sights on competing in the Champions 
Race-a cross-world gauntlet whose winner is listed among the greatest 
felrell pilots in history.
But behind the scenes, political factions and government conspiracies
 collide with Junar’s new plans. The young pilot suffers a horrific blow
 at the hands of the Zy-Adair-the notorious Sky Pirates. And soon, his 
perfect world is spiraling out of control.
From his unsuspecting alliance with the Inventors-dubious tinkerers 
and social outcasts-to his unlikely associations with the Brologi-the 
Chancellory Police-Junar must find a way to plead his case before the 
Chancellor of Aria-Prime and piece together a puzzle that threatens his 
entire world’s way of life.
