6 Ways to Where — R. Mac Wheeler

At eighteen it's tough to decide a life path when the threat of pandemic hangs over the world, your brother is the genius who engineered the plague, and you're repeatedly drawn into the fight against the terrorists spreading it. Plenty of people would kill an Abernathy on sight so it would be wise for Mar to visit the dojo, otherwise play invisible, but her brother is manipulating her into another adventure.

6 Ways to Where is Book 3 of the 6 Ways series.
