The Shibboleth is a 2014 young adult's novel by John Hornor Jacobs. It continues the story of teenagers, Shreve Cannon, and Jack Graves, who have psychic abilities.
A starred review in Booklist called it a "dyed-in-the-wool middle book [in a trilogy]", and said that "its chief achievement is to foment excitement for the finale",[1] while Kirkus Reviews described it as "a series of elongated plot twists that need to move [the] lead character from one place to the next".[2]
School Library Journal lauded its "engaging" prose, its "realistic, mature language" and its "cliff-hanger ending",[3]
while Horn Book Guides noted its "sheer weirdness" that "will captivate readers",[4] and Voice of Youth Advocates praised it as "a superb telling of what it means to be different".[5]
