Tempest by Julie Cross

19-year-old Jackson Meyer can time travel.  Not much, usually just back a few hours or days.  And when he does go back, nothing he does actually impacts the future - no one remembers interacting with him if it happened on one of his jumps, if he hurts himself he isn't seriously damaged when he gets back, and if he does something on one of his jumps, like break a window, that thing is undone when he gets back to the present.  It's not really serving a purpose, but he's having fun experimenting, and keeping it a secret from everyone but his science genius friend who is helping him figure out why it's happening and how to use it.  At least it is all fun until some people who also appear to be able to "jump" back in time show up at his girlfriend's college dor, attempt to kidnap Jackson, and kill his girlfriend in the struggle.  Now Jackson has jumped back 2 years, farther than he's jumped before, and no matter how hard he tries, he can't get back to his "real" time.  And the Enemies of Time are still after him.

Prepare to Die by Paul Tobin

Despite being at their mercy, Steve Clarke, aka superhero Reaver, is inexplicably given a boon by arch-nemesis Octagon and his cadre of supervillains, Eleventh Hour - instead of killing him outright, they grant him 2 weeks to take care of his affairs before he reports back to them to fight to the death.  Steve uses the two weeks to come to grips with how he became a superhero in the first place, the loss of superfriends, his own moral ambiguity at times, and to reunite with his high school love, the girl who got away (or was pushed away due to Steve's unanticipated mutation caused by a chemical spill which transformed some of the cars occupants and killed others).

Crossed, by Allie Condie

Sequel to Matched.

Ready Player One, by Ernest Cline

Lots and lots and LOTS of geek and pop culture references from the 80's, as a teenage boy and his cohorts/competition attempt to solve puzzles in an online game that will determine who controls the internet in a futuristic society that lives mainly online.  Full summary from the publisher after the break.  Good for advanced teens and adults interested in the tagged subjects.  2011.

The Poison Eaters, by Holly Black

Five Flavors of Dumb, by Antony John

Piper is a senior in high school - quiet, keeps to herself, captain of the chess team, gets good grades, the usual stuff expected from a "good girl" character in teen novels, but Piper's behavior is due in large part to her feeling isolated from her fellow students because she is deaf.  With hearing aids she can hear some things, but her hearing is not perfect, especially in crowds or when she can't also lip-read.  Her best friend, also deaf, has moved away, Piper's younger brother, a freshman, seems embarrassed by her desire for him to sign with her, and her parents have raided the college fund her deaf grandparents set up especially for Piper to attend a college for hearing impaired students - to pay for cochlear implants so her baby sister can hear and not be disabled like Piper.  She's frustrated with being different and that her parents, her dad in particular, seem to see her as broken.  In a moment of very frustrated, very un-Piper-like behavior, she challenges the lead singer of her school's Teen Battle of the Bands winner - she'll become their manager and get the band, named Dumb, a paying gig within 30 days. 

The Rise of Renegade X, by Chelsea M. Campbell

Damien Locke is all set for his 16th birthday - it's the day his life of crime officially begins.  It's basically a technicality - Damien's mom is the mad scientist Mistress of Mayhem, he is a shoe-in for Vilmore Academy, the ultimate school for teenage supervillains and he's already got his supervillain name picked out: Midnight Marauder.  But in Golden City, all supers have a letter appear on their hand on their 16th birthday to make it official - H for heroes and V for villains.  So imagine Damien's surprise when his V doesn't show up, but neither does an H; an X appears instead.

Incarceron, by Catherine Fisher

Finn is a "cell-born" member of a Scum gang in Incarceron, the living prison with millions of electronic eyes and torture chambers, designed to recycled and re-use everything, even the people who are imprisoned there.  Finn remembers nothing before waking up in a cell, apparently remade from DNA of others who died, but his flashes of memory of the outside world convince him that he belongs outside.

White Cat by Holly Black, Curse Workers, Bk. 1

It was extremely hard not to read ahead in this book because I wanted to know what was going to happen next.  Little clues and pieces of info get scattered out like breadcrumbs, drawing you on, making you want to keep reading.  I figured out some of the twists before they came, but not all, and not too much before they were revealed.

Will Grayson, Will Grayson

Told from alternating POV's, this story focuses on a few months in the lives of two teens with the same name who meet through change and whose lives intersect at the large point of Tiny Cooper, the best friend of one Will and the new boyfriend of the other Will. Themes include looking at what makes people friends, dealing with romantic interest, how people can be very different but still love each other, a bit about telling friends and family that you are gay and a bit about depression and mental illness in teens. Funny, witty, relationships told from a guy's point of view, matter of fact about homosexuality. Lots of IM and texts quoted.
