Full Circle — Frank Carey

Why does eating waffles with the family bring aliens bent on revenge out of the woodwork?

Since being exposed to nanorobots at the beginning of the 21st century, Lee Carstares has been a caretaker of Area 26, the alien animal sanctuary, husband to his Alue wife, Clare, and father to their five children. For the last two centuries, he has led a quiet life interspersed with periods of excitement where he and Clare have fought off alien invaders, battled demons, and corralled escaped creatures of all description. Today starts out no differently than most others, but it soon goes pear-shaped when an old adversary returns for a rematch. And all Lee wanted to do was take his family to breakfast.

Full Circle is the third book of the Prehistory of the League of Planetary Systems where feeding the livestock takes on a whole new meaning.
