Once upon a time, Dr. Emily Nichols--the academic kind, not the physician kind--was an eco-crusader who was shot with water cannons, hunted by poachers, and chased by a bulldozer. Now? Action Emily lives in a bland condo with gray walls and teaches disengaged students at a university alongside a risk-allergic boyfriend, asking herself every day: How did I get here?

Then one afternoon Emily and her best friend, people-pleasing real estate agent Liv Bennett, witness an attempted robbery at their local coffee shop that is foiled by a yoga mom wielding a baby stroller. Their hero attributes her bravery to a mysterious class called Fearless, Inc. Its enigmatic and dizzyingly muscular instructor, Zeus, is now fully committed to helping Emily and Liv overcome their fears, too--one thrilling self-help lesson at a time.

Along with a ragtag group of other wimps, Emily and Liv must embrace the passionately unconventional methods of the leader to harness their powers, gain a bracing new perspective on life, act on their impulses, and be the no-holds-barred anti-heroes of their dreams.
