Jodi Lynn Anderson is the kind of author that I trust. While she has never done anything truly mindblowing on the level of, say, Markus Zusak, she writes well and consistently. My personal favorites were her middle-grade May Bird series, but there was also Tiger Lily which I have wanted to reread almost since I finished reading it the first time.
May Bird being other-world fantasy, and Tiger Lily being glorified Peter Pan fanfiction, these of Anderson's offerings made me used to her fantastical side. Peaches takes up on the more realistic side, though the peach orchard that the novel's three protagonists - Leeda, Birdie, and Murphy - inhabit for a while might be more magical than even Neverland.
From the very first page, it's made apparent that Peaches is a novel for a slightly older teenage audience. The situations are more mature, but more than that, Anderson's style is more mature. It's solid and dependable with just the sweetest, slightest hint of magic - a lot like the story itself. Her characters are... they're basically flawless. I went from feeling meh about all three of them to rooting for them to live together forever, on the peach orchard, happily ever after, please.
It wasn't quite that simple, of course, but I still loved where the story went. It was meandering but not pointless, a little circumstantial but never in a way that made me want to suspend my suspension of disbelief. Anderson executed a balancing act that deserves applause and frequent return trips. And there are sequels!
