The Ring of Solomon is by Jonathan Stroud. A Bartimaeus novel, although not part of the original Bartimaeus trilogy. Bartimaeus, the beloved evil djinni, is a slave to an evil wizard in King Solomon's court. Then, as the result of an exciting series of events, he finds himself bound to a young female protector of the Queen of Sheba, who orders him to help her to assassinate King Solomon and steal his magic ring before he invades Sheba - but as with all things Bartimaeus, things are not at all what they seem. Fans of this series will not be disappointed.
