"Henkien teatterin lapset ("Children of the Spooky Theater") is a charming children’s novel series set in early 1900s Helsinki, starring twins Ottilia and Roland, who once performed in spiritualist shows. The book’s magical atmosphere will sweep you away! 
Tuutikki Tolonen’s new series exudes a mystical mood and plays with messages from the beyond. Netta Lehtola’s illustrations deliciously bring historical Helsinki to life. "
