Its been ten years since Payton Thatchers twin sister died in an accident, leaving the entire family to cope in whatever ways they could. No longer half of a pair, Payton reinvents herself as a partner in a successful party-planning business and is doing just fine - as long as she manages to hold her memories and her family at arms length. But with her middle sister Jillians engagement, Paytons partyplanning skills are called into action. Which means working alongside her opinionated oldest sister, Johanna, who always seems ready for a fight. They can only hope that a wedding might be just the occasion to heal the resentment and jealousy that divides them ... until a frightening diagnosis threatens Jillians plans and her future. As old wounds are reopened and the family faces the possibility of another tragedy, the Thatchers must decide if they will pull together or be driven further apart.
