Ripper, by Stefan Petrucha

Orphan Carver Young has some general fantasies about becoming a detective, and devours novels and stories about  great sleuths, as well as serialized and sensationalized mysteries.  When ex-Pinkerton Detective Albert Hawking, cranky, contentious, eccentric, brilliant, and crippled, offers to take Carver on as an apprentice to share all he knows, Carver is ecstatic, even though it means living (for a reason I never really understood) in a private floor at the top of a mental institution, and getting more questions, half-hints, and criticism from Hawking than direct answers.  Carver's first and main "case" is to figure out the identity and possibly location of his father based on a scrap of a letter sent to the orphanage many years before.  As part of this Hawking introduces him to the "New Pinkertons", an underground (literally) and top-secret detective agency endowed by Alan Pinkerton upon his death. Hawking was head of the agency until his injuries forced him to give the reins to another former Pinkerton agent, Tudd, who is devoted to "gadgets" and buys many, many new mechanical, electrical inventions to help the secret agents with their investigations, and who is obsessed with catching a murderer, convinced it is the return of Jack the Ripper.

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.

Gwen is 16 and lives with her mum, siblings, grandmother, aunt and cousin in an upperclass London neighborhood.  Her extended family doesn't pay much attention to her, focused on her cousin, believed to be the carrier of the time-travel gene that runs through her family and sure to show up very soon in the form of an abrupt trip to somewhere in the past.  But all is not as it seems.  Since a mathematical formula had worked out that Gwen's real birth  date was the birth date of the next time traveler, and her cousin was also born that day, Gwen's mum and (late) father secretly falsified her records to indicate Gwen was born the day before, allegedly in the hopes that she would be able to live a normal life (and since she was born at home with a midwife, no one was the wiser.

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).

The Book of Blood and Shadow by Robin Wasserman

Around the World in 100 Days, by Gary Blackwood

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.

Close to Famous, by Joan Bauer

13-year old Foster McFee and her mother leave Memphis in a hurry when her mom's Elvis-impersonator boyfriend gives mom a black eye.  Leaving with only the items they can fit in their car, which is pretty much everything they own, they end up randomly stopping in Culpepper, West Virginia.  With no other destination in mind, they decide to stay in Culpepper, at least for the rest of the summer, and meet and befriend some of the town's inhabitants.  Because it is a small town, of course many of the inhabitants are eccentric and quirky, but at least their quirks are a different than the usual fare:  Miss Charleena is a former movie star who is hiding out after losing her confidence when her husband left her for a younger woman, Angry Wayne, owner of Angry Wayne's Bar and Grill is...if not angry, at least crotchety and a bit cranky, and Macon is a budding documentarist, just a tweenage one without a camera.
