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.

The Book of Blood and Shadow by Robin Wasserman

Nora has a pretty good life - yes, her brother is still dead and her parents are still withdrawn into their own self-absorbed worlds, but she has made a new family of sorts, with bright, charming, boy-wonder Chris and his lovely, capricious girlfriend Adriane as her best friends, and moody, quiet, scholarly Max as her boyfriend.  She also has an engrossing translation project for a local professor to strengthen her link with Chris and Max - while they work on translating the "important" parts of an ancient mystical document the professor is obsessed with, Nora translates late 16th century letters from a young woman, stepdaughter to a great magician - busy work to the professor, but more and more fascinating to Nora.  When her translation of the letters leads to a new discovery, she never expects it to end with the professor insane, Chris dead, Adriane catatonic and Max gone and branded a murder...but that's what happens.

The Poison Eaters, by Holly Black

Please Ignore Vera Dietz, by A. S. King.

This book evoked mixed feelings in several friends, but overall, I liked it.  Vera seemed pretty realistic in terms of not wanting to/not being able to talk about her feelings about her mom leaving, her dad withdrawing and especially her best friend's abandonment and then death.  She also seemed realistic in her self-destructive behavior, needing an outlet for the things she couldn't figure out how to express otherwise.  My main quibble is that Vera seemed to get over her dabbling with alcohol pretty easily - maybe she wasn't a full-fledged alcoholic, but she was definitely using it as a crutch, and that need seemed to evaporate after getting blotto and beaten up at the work Christmas party.  That struck me as a pat way of dealing with her developing problem.

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.
