Manhunt: The 12-Day Chase for Lincoln's Killer by James L. Swanson

While this book starts with the basics of Booth's conspiracy (originally to kidnap Lincoln) and the details of the assassinations and attempted assassinations (Secretary of State William Seward and Vice President Andrew Johnson were also targeted), the majority of the narrative focuses on Booth's attempt to escape after the assassination (slowed by a broken leg) and the federal hunt to find him. The book is well-researched, and while it's not a scholarly text, there are notes at the back as well as an extensive bibliography for those seeking further information. I learned a lot from this book and I enjoyed reading it as well.
