Summer At Willow Lake by Susan Wiggs

Olivia Bellamy has traded her trendy Manhattan life for a summer renovating her family's crumbling holiday resort. Tempted by the hazy, nostalgic memories of summers past – childhood innocence and the romance and rivalries of her teens – it's the perfect place for Olivia to flee after her broken engagement. But what began as an escape may just be a new beginning.

As Olivia uncovers secrets buried thick with dust, one by one her family return, their lives as frayed at the edges as the resort. Her father and the mystery woman in the tatty black and white photograph. Uncle John, who's trying to be a father again to his teenage kids. Connor Davis, the first love she never forgot.

Laughter is ringing around Willow Lake once more. This could be Olivia's summer of a lifetime!
