The story

Ezra Rosen has been sixteen since the Black Death. His father fixes things, his mother can smell a lie, and his little sister Juni can hear a heart through a wall. As long as their hearts hum, none of them can age, get sick, or die.

But the hearts wear out. Every time one starts to fail, the family has to find a new star stone, in a new American city, in a new decade, one step ahead of the hunter. From 1927 Chicago to 1998 Los Angeles, each book is a chase, a mystery and a heist, and the whole saga is finished, so you can read it straight through to the end.
