The Cave of Nine Bears - Chronicles of a Magi, #3

Following every clue to find and destroy the sunstone before Benrah's forces discover they have a useless counterfeit and that the Magi forces still have the real one, as-well-as access to the information it contains, Mark abandons that quest to others in order to help LeOmi find the staff prophesied to be hers. At every turn their path is fraught with peril. The search for the sunstone and the hunt for the staff converge into a violent conflict amidst the backdrop of the American west that the Magi forces cannot afford to lose.
