If you like those and need some reccommendations:


Mark Tufo's Zombie Fallout, Lycan Fallout, Indian Hill, Book of Riley, pretty much anything by him
John O'Brien's A New World series and Shrouded World series (in collaboration with Tufo)
R.A. Salvatore's Emberverse series and Island in the Sea of Time (I haven't read his others, such as Peshawar Lancers)
J.L. Bourne's Day by Day Armageddon
The Sovereign Spirit Saga by David Forsyth
Ragnarok Rising by D.A. Roberts


There's other great books/series/authors in the genres, but those ones stick out!
