Hit And Fade
The second book in the Forgotten Ruin series, Hit And Fade features the timeshifted Rangers going against something close to the original Fuldapocalypse “mascot”. Not a zombie sorceress, but a lich, a zombie sorcerer. I guess his sister was off provoking a Third World War and disabling the nuclear warheads.
The book is very similar to its predecessor in terms of quality, which makes it a little hard to review (in contrast to the original). All of what I’ve said about the good and bad parts has been stated already, and it doesn’t feel that different. If I had to say something, I’d say that the contrivances in worldbuilding add up when repeated, and that there aren’t enough new good qualities to make up for that.
Still, this is not a bad book. Its flaws are not insurmountable, and if this was the first in the series that I’d read, I’d probably feel differently. If you want to see Rangers fighting a skeleton mage, you’re in the right place.
