33a -- Quark of Nature (part 1)

The third of four books in the Checkwolf series examines the aftereffects of the drama from the end of the previous book, as well as introducing a major new threat to the organization and city they are sworn to protect, all while the team tries to maintain unity within the ranks.

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 3 demonstrates a darker and more threatening tone than the previous two releases – which is no surprise in view of the concluding moments of Book 2.  The ability of the group to function as a team is put under a constant strain, reflecting the difficult times they are facing.
