The Map that Led to You by Ella Mcleod

A long time ago, a witch burst into flames. A pirate and a mermaid fell in love. A map was marked with a glowing X. And a Republic was born.
 
In the present day, two girls are given a history assignment: to try and piece together the rise and fall of the famous and corrupt pirate Republic, which once formed their island home. As Reggie and Maeve sift fact from fiction, they realise that everything they've been told about the Republic is wrong. That the problem with history being told by the victors is that a lot gets left out. That ancient legend might be uncomfortably close to home. As their tentative friendship deepens into something more, they realise that a magical world could be on their very doorstep – if only they could find the map...
 
Blending high-seas swashbuckling adventure, lyrical poetry and contemporary romance
The Map That Led To You is another genre-defying, intoxicatingly rich tale of myth and magic from Rapunzella author Ella McLeod.
