Is There a Better Book Than Tomb Raiders Notes: Ghost Blows Out the Lamp and the Hidden Code?

Are there any better books than "Tomb Raiders Notes", "Ghost Blowing the Lamp" and "Tibet Code". I have read the prequel of "The Stealing Pen" several times. I fell in love with the character of the little brother, the brotherhood of the Iron Triangle, and the wit and humor of the fat man, and his innocent love.
