Critical Reception

Reviews of Messenger’s works have been mixed. Kirkus found Keeper of the Lost Cities to be “wholesome shading to bland,” but with “exotic creatures and locales, plus an agreeable cast” and described Exile as a “cumbersome coming of age tale.”

The Publisher’s Weekly review of Let the Sky Fall did not like the story’s pacing and said that the “novel works best when Messenger’s characters are left to explore her vividly imagined world of wind, rather than just talk about it.” Kirkus was more positive, stating that “Characterization elevates this romance over similar offerings in a crowded genre.” Kirkus remained positive about Let the Storm Break, writing, “Witty, romantic and filled with personality — after the slow start.”
