Without Warning: Elite Guardians (Book 2)

Katie Singleton, a partner with the Elite Guardians Protection Agency, stumbles upon her next assignment quite by accident. Spotting blue lights at a familiar restaurant, she stops to investigate, only to discover that owner Daniel Matthews has become the target of someone who will go to any lengths to put him out of business. Daniel might be concerned, but he's not convinced that a bodyguard- and a female one at that- is necessary. A new attack and his niece's urgings are enough to make him reconsider. He and Katie must figure out who's behind the intimidation and threats- before a would-be killer strikes again.
