This is now the fourth book in a row that I have read about two people, with very difficult childhoods and copying mechanism, to find each other is their safe place. Penelope was raised by her grandparents after (she was told) that her mother abandoned her and her father was unknown. While she received lots of love from her grandfather, her grandmother was the opposed, very strict and oppressive. Rafe was raised in one bad foster home after another, but managed to build a global company specializing in fireworks. Penelope is building her business as an event planner and comes to Rafe after her celebrity bride decided last minute that she wants fireworks. Intrigued and remembering how he felt when he was building his business, he decided not only to take her business but to do it himself. They create their own fireworks and learn to trust each other. It was a pleasant read, but disappointing at the end when after Rafe has discovered the truth about Rachel's parents that we did not get to witness her meeting her father, who never knew she existed.
