Asia has always been the serious, got-it-all-under-control Swenson, who protected her sibling from childhood scrapes. Lucy, six years younger, made up for her mishaps with her infectious smile and enthusiasm. Now, giddily in love and about to be married, Lucy has never been happier-until she learns that Asia's breast cancer is back. How can she get excited about planning her future when her sister is fighting for her own?

Friends and family mean more than they ever have to Asia, and lately, her charming co-worker Brandon Peters has been popping up wherever she goes. Talk about timing: could Asia be falling in love for the first time in her life? With Lucy's help, she's going to seize each day-losing herself in giggles and adventures, opening herself up to new relationships and deeper connections. And nothing, absolutely nothing, will stop her from walking down the aisle as her sister's maid of honor.
