"Each of the three books is centered on a particular mystery – about a deathly shadow, a haunted cathedral, and a stolen jewel. Xan helps to solve these mysteries with his friends....  The three books are replete with twists and turns, which make for an action-packed story line. But there is also a great deal of subtlety, particularly in the way that the characters relate to one another and in the way that they relate to God, giving these books more depth than typical adolescent fiction." ~ CatholicMom.Com (see full review)
