Earth Warden by Tony James Slater

SPSFC

The Wardens are our planet's last line of defence.
Powerful warriors, they stand firm against every threat humanity faces.
It’s more than just a career – it’s a sacred calling…
But it comes with a very short life expectancy. Lord Kreon, Warden of the First Circle, has a problem.
He’s been forced to kill another apprentice, and he’s rapidly running out of candidates. In fact, there is precisely one left… Raised on modern-day Earth, Tristan knows nothing of the wider galaxy.
He’s been fighting just to survive, ever since the day his dad left for work – and never came home.
He’s always believed that there was more to life. That he could make a difference.
He’s about to discover that what you don’t know can not only hurt you, it can tear your world apart! Forcibly abducted, he has no choice but to join the hand-picked warriors of Lord Kreon’s team:
Kyra, a rainbow-haired mercenary with a tongue as sharp as her swords;
Blas, a gigantic super-soldier left for dead by his unit;
and Loader, a cargo handling robot with an incredible secret. All he wants are answers – but will he survive long enough to get them? Join Tris, as he’s catapulted into a universe beyond his wildest imagination. Where bizarre aliens threaten mankind, genetically engineered assassins lurk in the shadows, and the mysterious Wardens live by an ancient code…
Of sacrifice. With a healthy dose of Joss Whedon-style humour, fans of Firefly and The Expanse will love this fast-paced and action-packed space opera. Buckle up, brace yourself, and download Earth Warden today! ***Complete 5-book series available now! All books in Kindle Unlimited.***
