A taut, brilliantly conceived thriller with impeccable pacing bursting with ideas...For fans of noir-laden science fiction in the vein of Philip K. Dick that is in equal measures suspenseful, gripping, darkly funny and philosophically challenging.
-Kirkus Reviews

If you love roller coaster paced futuristic thrillers, you're gonna love this book! I finished it in 2 sittings (only because there is just SO much to take in)! O'Donnell gives you a very vivid, descriptive prose with a tightly woven plot, and characters that jump off the page !

Overall Kingdom was a quick read with a compelling narrative and surprisingly sympathetic characters that made me want to learn more about this Tiber City while freaking me out at the same time.

This was not a fast read and I really needed to pay attention while reading it. But that was no problem at all. O'Donnell's writing and worldbuilding makes sure you keep interested en flipping the pages to see what will happen next. This is the first installment in his Tiber City series and I must say Iím looking forward to his next installment
