There’s no obvious connection to the birthdays of illustrious dead presidents or to St. Valentine. But for whatever reason, February seems to be a big month for books about the environment. LIME hasn’t yet had the chance to read these hot-off-the-press titles, but here’s a quick look at three books on Planet-related themes.

Novelist Suzanne Matson’s The Tree Sitter tells the story of a college junior who forsakes her cozy Northeastern world to join a group of tree sitters (a la Julia Butterfly Hill) in an Oregon forest. The group’s activities become increasingly violent, tragedy strikes, and the protagonist, Julie, must weigh “whether her own life is an even exchange for the trees’,” according to Publishers Weekly. The PW review said of Matson’s novel: “thoughtfully told, this story of the all-encompassing blaze of first love and an uneasy eco-activism is surprising and honest.”
