Lucy Wagner Series by Claire Matthews

Lucy Wagner's ready for the future-her career's on track, and her relationship with Paul, her pediatrician boyfriend, seems headed for the alter. But when Paul reveals his infidelity, Lucy must pick up the pieces of her love life. Will training for an Extreme Adventure Race with her best friends Jen and Will help her rediscover her confidence? Or will she fall short of the finish line?

Jen Morales is fed up--work is stressful, her best friend Lucy is knee-deep in marriage plans, and her boyfriend Dax needs some work in the maturity department. When she gives Dax his walking papers in a fit of temper, she's left to pick up the pieces and navigate life on her own terms. But when living solo doesn't measure up to Jen's expectations, she's relieved to find that her friends, including her new office-mate Kevin, are there to give her a clue.
