Portals of Albion - Joshua Kern - Bog

Siblings with a secret. Portals to different worlds. A world in need of magic.
Zack and his younger sister, Zara, have had to fight for every scrap of food and luck that has ever come their way. All of that changes when Zack awakens as a Traveler.
As a Traveler, Zack holds the key to changing his small family's fractured fate, and for his sister, he'll risk everything.
The dangers that await him in the mystic realm of the portals, where ancient powers still linger, aren't the only thing he needs to be wary of. Nobles, both good and bad, have learned of them as well.
The portals provide a way to fight back, to become stronger than their foes, to capture the life they've always dreamed of.
Zack will do anything to keep his sister safe, and it's time to prove it.
Thankfully, magic has a way of evening the odds…
This series is set in the Game of Gods universe.
