A Study in Charlotte is a contemporary young adult mystery featuring a teenaged Holmes and Watson. They go by the names Charlotte and James (sometimes Jamie though he doesn't particularly like the nickname). The central conceit of A Study in Charlotte is that Sherlock Holmes, John Watson, and James Moriarty were all real people whose respective descendants, with a few exceptions, don't get along. This is not particularly surprising in the case of the Moriarty family, but even Holmeses and the Watsons keep their distances from one another.
Charlotte and James are direct descendants of Sherlock and John. Charlotte mirrors her ancestor in her brilliance and habits while James has a bit of an anger management problem. Though both were both born to English parents for reasons the two teenagers now
attend boarding school in Connecticut, where all the action takes place. That action begins with an obnoxious boy who turns up dead under suspicious circumstances. Given that James punched the obnoxious boy the day before after the boy made some very rude remarks about Charlotte, the two detectives quickly become the primary suspects.
A Study in Charlotte was entertaining but by no means a favorite. Much of the story revolves around various love related issues - unrequited love, first love, angry love. It's cute but not at all what I expected (or wanted) from a Sherlock Holmes story. There were also some serious issues (sexual assault, drug addiction) that were glossed over and could have been handled better.
This is the first in a series. Despite a few reservations I am intrigued enough to see where the story heads next.
