The Best of Men

"Epic Fantasy on a grand scale" British Fantasy Society  (http://www.britishfantasysociety.org/reviews/coincident-by-wilf-jones-ebook-review/)
Something is coming.
Seama Beltomé can feel it. He can see it.
The four nations of Asteranor are already at war or soon will be. But what’s coming is worse than that.
Seama is reading Haslem’s Song of Ages. Or whatever's left of it. An obscure history of mankind, it announced its presence by bursting into flames in the Escartine Library. The few pages rescued reveal a tantalising glimpse of the Earth’s deep past, a revelation of Ages and deeds unknown.
And they carry a dark warning:
what is forgotten cannot cease to have been,
a crime against existence cannot be undone,
and the banished will seek to return.
Seama has been summoned because the time has come.
Something more dangerous than death, an ancient evil, stands just beyond the gates of the world.
It waits only on a passage opened, a door unlocked.
Seama can hear the rattle of the keys.
Set on an Earth remade, The Best of Men is volume one of the Song of Ages trilogy, an epic fantasy of monsters, gods, warriors and wizards, of heedless villains and decent everyday people.
This debut novel from Wilf Jones marries the dark epic fantasy styles of George RR Martin and Jack Vance to the post-apocalyptic jaunts of Stephen Lawrence and Joe Abercrombie, with something of the Eddings Belgariad thrown in for good measure.
