Greenhouse Effect (n): the trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface. Annie Lennard has decided it's time. It's time to figure out what she really wants, who she really is, and what she hopes to do with her life. She quickly finds out that the best way to go about this is to open her mind and accept the warmth and wisdom of people she loves... letting those bits and pieces get trapped inside her own lower atmosphere until she's warm and wise too. For fans of All The Bright Places (Jennifer Niven) and I'll Give You the Sun (Jandy Nelson)
