Gears Of War: Anvil Gate [EPUB ebook] 

With the Locust Horde apparently destroyed, Jacinto’s survivors have begun to rebuild human society on their island stronghold. Raiding pirate gangs take a toll – but it’s nothing that Marcus Fenix and the Gears can’t handle. Then the terrifying life-forms they thought they’d left behind – the Lambent, creatures even the Locust feared – begin to advance across the planet. Gears and gangs must fight side by side to stop their deadliest enemy yet, falling back on the savage tactics of another bloody siege: Anvil Gate.
