The Undulating Mountain

When their parents fail to return home to their Manhattan apartment one evening, twelve year old Sophie Penn and her brothers William and Tom are left to navigate on their own in a city where technology has become unreliable, discombobulated bands of people roam the streets, fires erupt spontaneously on the rivers, and no one seems to be in charge. On a journey that takes them from the changed streets of their home city to the no less changed and mysterious Undulating Mountain where their grandmother Lupine lives, the children seek to right their out-of-balance world. It is a journey fraught with danger, and full of wonder and new friends.
