Madison hopes for normal life with her new boyfriend after an online scandal, but a school artifact under her care is stolen. Recovering it requires her friends to attempt a risky heist against a rival school on prom night.

Madison expects a quiet summer at the beach with her friends, but enemies have plans to disrupt it. Protecting herself requires her most ambitious scheme yet and an uneasy appeal to someone she never expected to trust.

Returning to the Hamptons after a breakup, Gemma hopes to make amends with former friend Hallie. Mistaken identity lets her conceal their troubled history, but attraction to Hallie's brother makes maintaining the deception increasingly difficult throughout the summer.

Hallie tells her side of the friendship that collapsed when Gemma interfered with their parents' relationship five years earlier. This companion short story explores the aftermath of that betrayal and the experiences behind Hallie's response to her former friend.

Humiliated by Hallie's revenge, Gemma decides to retaliate while juggling an ice-cream job and tangled romantic prospects. Their escalating feud involves schemes and stolen identities, turning an already complicated Hamptons summer into an increasingly personal contest.
