Boston College alumnus Chuck Abdella concludes his fantasy book series with A Flicker of Hope. In the Outcasts series’ fourth book, the heroes find themselves questioning whether the world is even worth saving and facing doubt about themselves and each other. But, according to the publisher, “the power of friendship endures. For beneath an ocean of darkness, there is always a flicker of hope.” When he is not writing, Abdella is teaching history at St. John’s High School in Shrewsbury, Mass.
