The Horus Heresy Book 42 Death Guard. Battle-Captain. Knight Errant. Agentia Primus. Hero. Nathaniel Garro's journey has been long and hard and now, you can read it all in one book, embellished and expanded from the original audio dramas. READ IT BECAUSE Garro hasn't reached the end of his journey quite yet – the Siege of Terra awaits him – but for the very first time, you can read his entire saga in a single volume, from his first mission as an agent of the Sigillite to his decision to break away and seek his own destiny. THE STORY From out of the shadows of the Silent War, a hero emerges. Clad all in grey, an errant warrior of the Legiones Astartes kneels before the Regent of Terra, and accepts a solemn new duty – Battle-Captain Garro, once commander of the Eisenstein, now Agentia Primus of Malcador the Sigillite. From the desolation of Isstvan to the halls of the Imperial Palace itself, he stands as a paragon of loyalty and protector of the innocent, ever ready to strike back at the traitorous allies of the Warmaster. But Garro is walking a path of his own, one that may lead him to question his own place in the Imperium... and what if he, too, should falter? This book contains James Swallow’s complete saga of Nathaniel Garro in the Horus Heresy – the audio drama series is embellished and expanded in prose, with additional scenes to represent the author’s original vision. This all serves as prelude to the events of the novella Vow of Faith, bringing Garro closer to his inescapable destiny as the first true martyr of the Lectitio Divinitatus. Written by James Swallow
