Olivia Bellamy reluctantly trades a trendy Manhattan summer for her family's old resort camp in the Catskills to renovate the bungalow colony for her grandparents, who want one last summer together filled with fun, friends and family. A posh resort in its heyday, the camp is now in disarray and Olivia is forced to hire contractor Connor Davis-- a still-smoldering flame from her own summers at camp.

But as the days grow warm, not even the inviting blue waters of Willow Lake can cool the passions flaring or keep shocking secrets at bay. The nostalgic joy of summers past breathes new promise into a special place and people...a promise meant to last long after the season ends.
