Agnes Hussein, descendant of the last sultan of Singapore and the last surviving member of her immediate family, has grown up among her eccentric relatives in the crumbling Kampong Glam palace, a once-opulent relic given to her family in exchange for handing over Singapore to the British.

Now Agnes is seventeen and her family has fallen into genteel poverty, surviving on her grandfather's pension and the meager income they receive from a varied cast of boarders. As outside forces conspire to steal the palace out from under them, Agnes struggles to save her family and finds bravery, love, and loyalty in the most unexpected places. The Moonlight Palace is a coming-of-age tale rich with historical detail and unforgettable characters set against the backdrop of dazzling 1920s Singapore.
