Sizzling Sixteen, by Janet Evanovich

Silly sixteen. More of the same, with less flavor and appeal. Stephanie's indecision about choosing between Ranger and Morelli has led to books as celibate and boring as the Twilight series (with which I can actually imagine some audience overlap, so ugh to that), Lula, Connie, etc have become cariacatures rather than characters, previous plot lines have been dropped altogether, and the charm that held it all together, like, say, the marshmallow in Rice Crispie bars, has dried up, leaving nothing but a crackling pile of stale nuggets.
