Any good mystery/adventure book recommendations?

Dangerous Days: The Autobiography of a Photojournalist, and its sequel, Blades: The Autobiography of a Rescue-Helicopter Pilot, both by J. William Turner. Realistic fiction about teens in several dramatic life and death situations set in Australia, England and California during the years 1981-1982 and 1995-2001. Each is written as a series of four shorter novels (about 100 pages per novel) inside a single cover dealing with teenage, adult and social themes.
