Mae (Mae #1)

Mae's older sister Abbie ran away from home eight years ago. Long enough that Mae has gotten on with her life, and come to terms with being her aging father's only family. So when Abbie reappears one night, wearing an outlandish outfit complete with golden axes at each hip, and explaining that she's been living on another world - where she was queen of a species of talking cats - Mae is sure her sister's lost her mind. That is, until strange and menacing creatures start showing up in Mae's hometown... and her father suddenly disappears. Now Mae must follow a sister she barely knows into a world she never could have imagined to save her only family, and maybe discover something about herself in the process.
