This classic work of fantasy begins with scholar Ludwig Horace Holly being visited by an old friend who is ailing. The friend passes the guardianship of his 5-year-old son on to Holly. Fast forward twenty-five years: the hapless orphan is now a handsome and capable young man (Leo) whose past holds a series of remarkable secrets. Holly and Leo travel to Africa to unravel Leo’s family secrets and encounter a seemingly immortal tribal leader, Ayesha, whose power and influence are virtually impossible to overcome.
