'It's the beginning of the 20th century; the age of scientific progress. But for Venice the future looks bleak. A conference of scientists assembles to address the problems, among whose delegates are the parents of eleven-year-old Teodora. Within days of her arrival, she is subsumed into the secret life of Venice: a world in which salty-tongued mermaids run subversive printing presses, ghosts good and bad patrol the streets and librarians turn fluidly into cats. A battle against forces determined to destroy the city once and for all quickly ensues. Only Teo, the undrowned child who survived a tragic accident as a baby, can go "between-the-linings" to subvert evil and restore order.'
