An excellent book written by Kate Novak and Jeff Grubb. It is the first in The Finder's Stone Trilogy and is the story of a young mercenary who has been marked with these strange blue symbols. She wakes up in a strange place with no memory of how she got there. She almost immediately meets her soon-to-be travelling companion, ]Dragonbait]. Early in the book we discover that our heroine, Alias, bears the marks of several nefarious guilds and mages that wish to use her body for their purposes.
Published in 1988 by TSR, this book is the inspiration for the aforementioned game Curse of the Azure Bonds.
