Reviews of Fly on the Wall

From TeenReads:
"The novel is fast paced, hysterically funny, and a pleasure to read."

The Horn Book magazine says, of FLY ON THE WALL:
"This unexpectedly sharp comedy charts its own metamorphosis -- from teen angst ("Life as an Artificial Redhead") to surreal wish-fulfillment fantasy ("Life as a Vermin") and beyond ("Life as a Superhero"). Gretchen Yee, a well-intentioned but self-absorbed teen smarting over her parents' sudden divorce, wishes she could be "a fly on the wall of the boys' locker room" -- and then has to deal with the consequences when her wish inexplicably comes true. Stuck in observer mode (upon pain of squishy death), she learns to consider others' perspectives, enabling her to mend fences with her father, play matchmaker for her love-struck best friend, and connect with her own crush upon her return to human form."

From The Bulletin of the Center for Children's Books:
"The stylish text (rendered nearly multivocal by the periodic font changes) combined with Gretchen's frank fascination with the oddity and then the humanity of the male body and psyche are a rare treat."

From Publishers Weekly:
"Narrator Gretchen Yee will grab readers from the first page with her snappy commentary."

From School Library Journal:
"When the insect character emerges, Lockhart's writing style moves from prose to near poetry as she weaves in and out of Gretchen's mind. This technique allows readers to know what the protagonist is thinking, keeps the pace of the quickly moving story, and suspends disbelief with the very absurd concept. Although containing some strong language and mature situations, this novel is a good choice for teens who are unsure of their place in the world, including reluctant readers."
