Uki and the Swamp Spirit by Kieran Larwood

After a chance encounter

the girl and boy are caught up in a wild dash to rescue the mysterious monarch

No one has ever accused Sage Cunningham of being easily distracted

They are told the Franks have fled to Switzerland

Trauma is a fact of life

the girl's name is Anne Frank and for seven blissful years the inseparable pair navigate school
