Marnie is just 35 when her boyfriend, Brian, drops dead of a sudden heart attack. Stunned by his death, Marnie finds her greatest grief is for Troy, Brian's son whom she has raised as her own since he was a kindergartener. When he is reclaimed by his train wreck of a birth mother, Troy's departure drives Marnie to a grief group at the local rec center. There she finds unexpected allies, three strangers who join her in an impulsive road trip from Wisconsin to Las Vegas to reconnect with Troy. Along for the ride are fifty-something Rita, prim and ladylike on the outside, seething with rage on the inside over the murder of her daughter; Laverne, Marnie's introverted landlady who is crippled by grief for her late husband; and Jazzy, a psychic driven to the grief group by an unseen voice. Together they embark on the adventure of their lives, a journey toward healing, friendship, and love.
