Plot summary
The protagonists of the novel, Mia Carrington and Evander "Vander" Brody, were childhood acquaintances whose parents were involved in a long-term affair. The prologue details Mia's humiliation when, at age 15, another acquaintance ridicules her for writing a love poem to Vander.

Thirteen years later, both are still single. Vander is now the Duke of Pindar, but eschews polite society to train racehorses at his estate. Mia is a very successful romance novelist, writing under a pen name. After her fiance leaves her at the altar, Mia is desperate. If she does not marry within the month, custody of her crippled nephew, Charlie, will revert to his evil uncle. Seeing few options for herself, Mia blackmails Vander into marriage. In a fit of anger, he announces he will grant her only four nights per year; Mia agrees to those terms.

After the ceremony, Vander learns that Mia intends the marriage to be temporary. By now intrigued by her and quickly becoming attached to Charlie, Vander refuses to grant her an annulment. He insists on his four nights, and soon finds himself in love with his new wife.
