Ever since she fell into the Source of all magic, Tourmaline seems to have developed strange new powers that are causing chaos. She can't work out how to control them and it's exhausting hiding them from everyone (except her best friends George and Mai). Then Tourmaline receives a mysterious postcard, promising her solutions and sending her on quests to amazing places. But who has sent Tourmaline the card? And will the adventure be worth the price for answers? The second book in a fun, feminist fantasy adventure series, with a protagonist that flies off the page and into readers' imaginations. Perfect for fans of Katherine Rundell, Vashti Hardy and Abi Elphinstone
