Darkest Day — Colleen Vanderlinden

One moment, one mistake, changed Jolene Faraday's life forever. Devoted entirely now to bringing down the super villain known as Killjoy, she spends every waking moment working toward his downfall - and the rest of the time trying to come to terms with what her life has become. Somebody's about to have a bad day... Nightmares, guilt, and questions of her own morality notwithstanding, Jolene, A.K.A. Daystar, is becoming the hero she swore she'd be, and StrikeForce, under Portia's leadership, is earning a measure of respectability from friend and foe alike. That is, until questions about Jolene's involvement in a certain super villain's death come to light, along with increasing pressure for her to answer questions about her shadowy past. All of it is background noise, a distraction from her hunt for Killjoy and his team. And when they threaten yet another person she cares for, Jolene becomes nothing less than Killjoy and company's worst nightmare.
