OUTSHINE needs a cover! OUTSHINE is a slightly funny but mostly dark novel for the Young Adult crowd (which means the cover must appeal to teens as well as the large number of adults who read teen fiction)
I prefer covers without people in the design, or if there are people they are shadows or silhouettes or fuzzy. Covers that I like include the Maze Runner trilogy by James Dashem, I am the Messenger by Zusak, Gathering Water, Awaken, the Divergent triology (NOT the new cover for Divergent now that its a movie but the old cover that matches Allegiant and Insurgent)
This book is a little dark, so even through the name is OUTSHINE, the cover should be mostly dark with just a small amount of "shine". Imagery that figures in the book includes a needle/syringe, vials of meds, rabbits (less important than syringe) and the landscape: basalt cliffs, sage dessert.
One of the characters has a special power where, if someone lies, he'll know the truth. The words will just appear in his head. SO, imagery where there are indistinct words floating in the background would work, esp if words are related to genes/DNA research.
When agoraphobic GABE, 17, and his outgoing nemesis JESSA, 16, go on a moonlit road trip to locate Gabe’s missing brother, the two teens discover they are both hiding unnatural abilities: Gabe is a living lie detector and Jessa is a kick-ass powerhouse pretending to be a delicate diva.
Gabe’s sole reason for searching for WATTS, his overbearing younger brother, is to clear his own name: he’s been framed for Watts’ alleged murder. Jessa is after Watts because she is, well, after him.
They locate Watts with a twisted eugenicist named DEACON who aims to save the planet from human overpopulation. There, the teens learn they are “Upgrades,” an improved version of the human race created through genetic manipulation and bio-technology specifically to aid Deacon’s plan. Deacon promises them that, under his care, they can finally live openly as the genetically-altered freaks that they are.
Jessa and Gabe are not taken in by Deacon’s slick words. They escape, bringing a drugged Watts with them. When the drugs wear off, Watts betrays them only to be reined back in by Jessa (with the help of another syringe of medication.) Medicated Watts is trustworthy, safe, and devoted to Jessa.
Jessa, however, has become charmed by Gabe’s innate goodness and dedication to always doing the right thing. When Watts becomes aware of Jessa’s feelings for his brother, tensions clash, leading to a brutal fight in which Gabe does not do the right thing, shaking Jessa’s respect for him and leaving her wondering which of the two brothers she can really trust.
