The president's daughter : a thriller / Bill Clinton, James Patterson.

"Matthew Keating, a one-time Navy SEAL--and a past president--has always defended his family as staunchly as he has his country. Now those defenses are under attack. A madman abducts Keating's teenage daughter, Melanie--turning every parent's deepest fear into a matter of national security. As the world watches in real time, Keating embarks on a one-man special-ops mission that tests his strengths: as a leader, a warrior, and a father"-- Provided by publisher.
