Looking through the 2013 YA releases, I noticed that there were quite a few titles that deal with doubles (either in the form of clones, lookalikes, etc.) or parallel (i.e. also doubled) timelines (such as alternate universes/realities).
Addison Coleman’s life is one big “What if?” As a Searcher, whenever Addie is faced with a choice, she can look into the future and see both outcomes. It’s the ultimate insurance plan against disaster. Or so she thought. When Addie’s parents ambush her with the news of their divorce, she has to pick who she wants to live with—her father, who is leaving the paranormal compound to live among the “Norms,” or her mother, who is staying in the life Addie has always known. Addie loves her life just as it is, so her answer should be easy. One Search six weeks into the future proves it’s not.
In one potential future, Addie is adjusting to life outside the Compound as the new girl in a Norm high school where she meets Trevor, a cute, sensitive artist who understands her. In the other path, Addie is being pursued by the hottest guy in school—but she never wanted to be a quarterback’s girlfriend. When Addie’s father is asked to consult on a murder in the Compound, she’s unwittingly drawn into a dangerous game that threatens everything she holds dear. With love and loss in both lives, it all comes down to which reality she’s willing to live through . . . and who she can’t live without.
The consequence of this one decision will split Caroline's fate into two separate paths--and she's about to live them both.
Friendships are tested and family drama hits an all-new high as Caroline attempts to rebuild old relationships, and even make a few new ones. If she stays, her longtime crush, Joel, might finally notice her, but if she goes, Chris, the charming college boy, might prove to be everything she's ever wanted.
Though there are two distinct ways for her fate to unfold, there is only one happy ending...
You. Your best friend. Every person you know.
Many worlds. Many lives--infinite possibilities.
Welcome to the multiverse.
Sixteen-year-old Sasha Lawson has only ever known one small, ordinary life. When she was young, she loved her grandfather's stories of parallel worlds inhabited by girls who looked like her but led totally different lives. Sasha never believed such worlds were real--until now, when she finds herself thrust into one against her will.
To prevent imminent war, Sasha must slip into the life of an alternate version of herself, a princess who has vanished on the eve of her arranged marriage. If Sasha succeeds in fooling everyone, she will be returned home; if she fails, she'll be trapped in another girl's life forever. As time runs out, Sasha finds herself torn between two worlds, two lives, and two young men vying for her love--one who knows her secret, and one who thinks she's someone she's not.
The first book in the Many-Worlds Trilogy, Tandem is a riveting saga of love and betrayal set in parallel universes in which nothing--and no one--is what it seems.
Finally, she’s promised a cure: minor surgery to burn out the overactive area of her brain. But on the eve of the procedure, she discovers the shocking truth behind her hallucinations: she’s been seeing the world through another girl’s eyes.
Elissa follows her visions, and finds a battered, broken girl on the run. A girl—Lin—who looks exactly like Elissa, down to the matching bruises. The twin sister she never knew existed.
Now, Elissa and Lin are on the run from a government who will stop at nothing to reclaim Lin and protect the dangerous secrets she could expose—secrets that would shake the very foundation of their world.
Riveting, thought-provoking and utterly compelling, Linked will make you question what it really means to be human.
Then Lizzie meets Sean Kelly, a guy who seems to see into her very soul. As their relationship develops, Lizzie realizes that she's not a carbon copy of her sisters; she's an individual with unique dreams and desires, and digging deeper into her background, Lizzie begins to dismantle the delicate balance of an unusual family that only science could have created.
Tessa hates everything about being an impostor—the stress, the danger, the deceit—but loves playing the role of a normal girl. As Madison, she finds friends, romance, and the kind of loving family she’d do anything to keep. Amid action, suspense, and a ticking clock, this super-human comes to a very human conclusion: even a girl who can look like anyone struggles the most with being herself.
With the help of Caitlin, her science-savvy BFF, Abby discovers that this new reality is the result of a cosmic collision of parallel universes that has Abby living an alternate version of her life. And not only that: Abby's life changes every time her parallel self makes a new choice. Meanwhile, her parallel is living out Abby's senior year of high school and falling for someone Abby's never even met.
As she struggles to navigate her ever-shifting existence, forced to live out the consequences of a path she didn't choose, Abby must let go of the Plan and learn to focus on the present, without losing sight of who she is, the boy who might just be her soul mate, and the destiny that's finally within reach.
