Kirkus Reviews referred to Tomorrow Wendy as a "steamy tale of emergent sexuality". Discussing the novel's characters, they noted that the adults in the book are "negligent or completely clueless" but highlighted how the main character had a "saving sense of irony", as well as "a keen appreciation for love's ambiguities and complexities".[1]
Publishers Weekly critiqued both the setting and character development, noting that the author's "depiction of privileged, nihilistic teens living life in the fast lane [...] appears more L.A.-ish than its Long Island setting might allow." Further, they found that the narrator's "rough language and hard-edged attitude toward sex can seem calculated". Compared to Stoehr's earlier novel's, however, they found that "the grittier elements of the story are in clearer service of a theme and message, and when the strands of the plot come together, the impact has force and vigor".[2]
