A fast-paced psychological crime thriller by James Patterson and Howard Roughan, first published in 2005. Combining serial murder, romance, and high-stakes investigation, it is one of Patterson's most addictive standalone thrillers.

The novel follows Nora Sinclair, a beautiful, intelligent, and extraordinarily successful investment banker who appears to have the perfect life. Charming and sophisticated, she quickly wins the trust and affection of wealthy, powerful men. But behind her glamorous façade lies a deadly secret.

After each whirlwind romance and lavish honeymoon, Nora's husbands begin to die under mysterious circumstances. Their deaths appear accidental or natural, allowing her to inherit their fortunes while remaining above suspicion. As the body count grows, the pattern attracts the attention of FBI agent John O'Hara, a determined investigator haunted by his own personal tragedies.

O'Hara becomes convinced that Nora is a serial killer, but proving her guilt is another matter. As he gets closer to uncovering the truth, he finds himself drawn into a dangerous psychological battle with a woman who is every bit as brilliant and manipulative as he is relentless. The investigation becomes a tense cat-and-mouse game filled with deception, obsession, unexpected twists, and moral ambiguity.

With short, punchy chapters and relentless pacing, Honeymoon delivers the trademark James Patterson reading experience while exploring themes of greed, manipulation, obsession, trust, and the hidden darkness beneath outward perfection.
