Dark Inheritance. Dark Series, #1

For six hundred years, the McAlister family has kept a secret - and paid for it in blood. Cole thought his grandfather's stories were entertainment. The dying Scottish warrior. The ship that fell from the sky. The thing he pulled from the crater that changed everything. They weren't stories. Now Cole is sixteen, the aliens are real, and the fight his family has been fighting since the fifteenth century just landed in his backyard. Armed with an ancient orb that chooses its guardian, Cole has one chance to end what Duncan McAlister could only survive. Some inheritances can't be walked away from. Some need to end.
