Vulkanherzen.

Marc Steinhauer meets Stella again after 20 years. Back then, she broke his heart, but now Stella asks the volcano researcher for help: her daughter has disappeared in Tenerife and Marc is supposed to help her find Mia. But Marc doesn't want to get involved at first – after all, Stella simply left him back then. But Stella has an ace up her sleeve, and the two set off on a search together.
