Jessica is a new lawyer, her boss calls her drunk and because she is still a flunky she gets up in the middle of the night to track down the first lady. After she finds her and gets her in the car, somebody chases them and everyone but Jessica ends up dead in the car accident. While in the hospital someone tries to kill Jessica, a secret service agent Mark believes her and tries to keep her safe. When Marks car blows up when both of them were supposed to be in it, they find out that it is the Secret Service trying to kill them. Mark and Jessica have to find out what the first lady was running from, who is really trying to kill them and deal with their attraction to each other. Jessica is a normal woman; she works hard helps to support her mother and sister. She isn't outrageously beautiful; she wears glasses and isn’t stick skinny. Mark is a hot agent with an ex-wife and a teenage daughter, he has relationship issues. He is very good at his job, outside of his daughter that is the only thing that matters to him, until Jessica. Pursuit is a fast paced, what is going to happen next and who really did it book. The story line is actually believable, with just enough irrationality thrown in to keep things interesting. I loved how the relationship between Mark and Jessica developed; they are so different from each other. The mystery of who was trying to kill them kept me guessing right up to the end. I loved this book and can't wait to read the next one.
