Azure Bonds. Finder's Stone Trilogy

Alias is a sell-sword, a warrior-for-hire, and an adventuress-and she's in big trouble-in this epic fantasy novel set in Dungeons & Dragons' Forgotten Realms! When Alias wakes with a series of twisting, magical blue sigils inscribed on her arms, she has no memory of how she got them. Determined to learn the nature of the mysterious tattoo, Alias joins forces with an unlikely group of companions: the halfling bard, Ruskettle; the southern mage, Akabar; and the oddly silent lizard-man, Dragonbait.
With their help, she discovers the symbols hold the key to her very existence. But those responsible for the sigils aren't keen on Alias's continued good health .
