Minerva Wakes by Holly Lisle
This is a light, fluffy 80/90s type of fantasy (i.e. a bit old fashioned) but still enjoyable provided you aren't looking for anything serious or dark. This story has humour; some serious bits; a quest; a pissed off mommy; a Wheaties chomping, beer-swilling dragon; magic rings; someone called the Unweaver; a portal fantasy land; and a moral.
NOTE 1: The characters in this novel make use of some "colourful" language.
NOTE 2: This is a standalone novel!!! No never-ending, unending series here.
NOTE 3: I read the revised edition of the book published by the author in 2016.
