Masquerade, thankfully, keeps the Maine tang and twang to a minimum while telling a perfectly pleasant story even though there's not much else up the sleeve of its domino. Monica and Martin, orphaned, and en route to their Aunt Naomi, whom they hate but do not know, pose as the children of their father's best friend to stop off at the long-closed up old Sea House on the Maine coast. Sea House has several legends -- a curse -- and a Monster, as well as the realities of whispering noises, a disappearing chess set, and a trap door to the attic. Monica and Martin spend a good deal of time exploring outdoors and indoors with the caretaker's grandson, Homer, whom they like and whose final exposure disappoints them. But then they also learn a little more about people and face-value judgements at the end. Girls will find it eminently likable.
