Jonah and Katherine come face to face with Albert Einstein in the
fifth book of the New York Times bestselling The Missing series.
Jonah and Katherine are accustomed to traveling through time, but when
learn they next have to return Albert Einstein's daughter to history,
they think it's a joke--they've only heard of his sons. But it turns out
that Albert Einstein really did have a daughter, Lieserl, whose 1902
birth and subsequent disappearance was shrouded in mystery. Lieserl was
presumed to have died of scarlet fever as an infant. But when Jonah and
Katherine return to the early 1900s to fix history, one of Lieserl's
parents seems to understand entirely too much about time travel and what
Jonah and Katherine are doing. It's not Lieserl's father, either--it's
her mother, Mileva. And Mileva has no intention of letting her daughter
disappear.
