Ink Mage

Ink Mage - Victor Gischler Fairly standard fantasy story of invaders killing a duke, only his daughter saved and vowing revenge etc.

The part that lifts it up is the magic - rather than learning spells in books, some people can have it tattooed into their skin. Finding the people who can do it is part of the quest that Rina finds herself on.

Good characters and the chapters always leave you wanting to find out what happens next.
