Most important: This is not a three-book series but a single large novel published in three volumes. This should not surprise anyone as the author's own blurb warns the readers against cliffhangers in volumes 1 and 2. You will be paying about 8$ for the whole story, but it's about 700 Kindle pages so that's not excessive. Get the boxset, as you will definitely want to keep reading after the first (free) book.
Quirky and engaging and sometimes charming characters inhabit picturesque Castle Cove. Among these, baby sister Paige was, for me, the best-drawn character, being a perfect thirteen-year old sweet little brat. The lead is the sympathetically-penned Charlotte aka 'Ruby'. The plot is a tumbleweed - a fast moving thicket, blown briskly along by the variably smart, caring, air-headed, scheming Not-Ruby (i.e. Charlotte). The story is more or less character driven and is cleverly played out. Each volume centres around its own focal mystery or point of tension, but the story blows right on from one to the next, with no overlap.
While Charlotte's character seemed a little inconsistent in maturity at times, there was no question but that I was rooting for her all the way. The con-artist parents, however, were noticeably flat villains, especially when viewed in contrast against other characters like the lively Tabby, embattled Ben, Gravy the three-legged cat, etc, etc, etc (the list is long!) Heartthrob Deputy Jared is entirely too flawless.
Four stars rather than five mainly for the variable strength of characterization, and because I feel that this should really be marketed as one book rather than three. Strongly recommended for YA fiction fans.
