An upgrade for the base; plus, Checkwolf unknowingly finds themselves in the sights of an enemy.

16 -- Raven (part 2)

The second of four books about the fictional crimefighting team known as Checkwolf picks up directly after the first.  The members of Checkwolf get a chance to meet a childhood idol, expand their team, and encounter new strangeness as they work to make the city they live in safer, one criminal at a time.

The Checkwolf series is a collection of stories chronicling the activities of Checkwolf's third phase, from its mainstream recognition to its full integration.

Book 2 features a mix of different kinds of stories, including appearances by other characters in the Checkwolf universe.  After becoming familiar with the mission and methods of Checkwolf in Book 1, the slightly different feel and perspective of many of these stories help to reflect the maturation of the group as a force in the fictional city of Kewanee.
