By the 5th book in the series, it is pretty clear what you get from a Gaunt's Ghosts book. Dan Abnett writes a intense, and action packed story, that does an amazing job a weaving larger conflicts, but primarily through zoomed in, squad to squad action, which makes the fights feel cramped where every casualty counts.

The real strength of the series flows from the variety and spirit Abnett manages to give to individual Ghosts, this makes them more then just numbers, and each death hits hard.

In The Guns of Tanith we get some excellent exploration of the ways the Verghasts and Tanith are joining (or not joining) together. And characters create some tension and problems for Gaunt, beyond just the problems of combat.

A great read as always for Gaunt's Ghosts.
