There is a little bit of underage drinking in this, but it doesn't end well for Frances (she call's Mason and is a teary-eyed drunk, and also loses her phone). The romance is clean, so this could be read by younger readers as well. Frances' attempt to connect with several different boys, and her feelings of awkwardness while doing so, will resonate with teen readers.
Readers who liked the bicycle adventure in Jennifer Bradbury's Shift or Diana Renn's Latitude Zero will love the description of cross country biking. Downsides, like spandex shorts, protein cubes and road rash all make a prominent appearance, but the camaraderie of the road is evident as well. Because of the extent of Stella's injuries, and their impact not only on Stella but on Frances as well, this is also a good choice for readers who like problem novels by authors such as Lurlene McDaniel, Sarah Dessen, and Susane Colasanti.
It's unfortunate that this is only available in paperback-- I'm a big fan of biking myself, and the scene where Frances and her date go to prom on their bikes makes this a title that I can't wait to hand to readers!
