Mercia is triumphant. Her king is safe. But Wessex was never Mercia’s only enemy.
Tamworth, AD836Following a brutally cold winter, King Wiglaf of Mercia is in the ascendancy. Even Wessex’s Archbishop of Canterbury extraordinarily ventures to Mercia to broker a religious accord. But,can the hard-won peace prevail?
Viking raiders threaten Wessex. These blood-thirsty warriors are fast, skilful and have no reticence about killing those who stand in their way. Their aim isn’t to rule but to overwhelm, slaughter and take ill-gotten wealth.
King Wiglaf is no fool. As the Vikings push to overwhelm Wessex, Mercia’s lands look insecure. King Wiglaf needs the shields of Mercia’s warriors to prevent the overwhelming advancement of their deadliest enemy yet.
To save Mercia, Icel must first prevail over the two men who mean to end his life; King Ecgberht of Wessex and his son, Æthelwulf of Kent and only then the marauding Viking army for whom boundaries have no meaning.
An action packed, thrilling historical adventure perfect for the fans of Bernard Cornwell and Matthew Harffy.

My Thoughts
Plot
In Shield of Mercia we return to a busy action-packed plot. War is on the doorstep, and the number of enemies keeps rising. Icel, a character who you may recall from Son of Mercia, aimed to be a healer. Instead, he became a renowned warrior. He always manages to find himself in the thick of the action, and in Shield of Mercia, in more danger than any book to date.
The gripping storyline and constant question of who could be trusted kept high tension throughout the plot. When eventually the pot boils over, we are treated to numerous battle scenes and conflicts that have us on the edge of our seat!
Setting
Events in Shield of Mercia are much like previous books in that travel is a greater element of the plot. Betrayal of Mercia felt like a bit of an exception to that rule, and I’m enjoying being back in the thick of the action.
I love this series for its truly country spanning narratives. The political and geographical context of the story is really interesting and far more dynamic than we are today. It’s a great backdrop at the best of times, as life in Britain was far from peaceful anyway. Add Viking raiders into this already tumultuous era and you get an unputdownable action-packed historical fiction novel/series! As I can attest to – I read 75% of this book in one evening!
Characters
Uncertainty between Mercian and Wessex people is rife in Shield of Mercia. The two fractious communities come together in order to oust a Viking enemy. Trust, however, does not come easily. Icel, our main protagonist of the series, has more reason to be both suspicious and wary than ever.
This feeds into a good portion of the plot, so the development of the characters and wider world within works hand-in-hand with driving the plot forward. It’s not therefore one at the expense of the other, but a great balance!
Icel remains one of my favourite historical fiction characters in this period. He is so well-rounded and unlike your stereotypical warrior. His character arc is unique and even so many books on from his humble beginning in Son of Mercia, his core character values are still well-defined and fit into the man he has become out of necessity.
Narrative Style
Shield of Mercia is very easy to read – as I’ve already alluded to, I read most of the book in one go. The style of narrative lends itself to a storytelling structure. With just one point of view, we’re able to get a deeper sense of Icel’s perspective on events.
Rightly or wrongly, his views shape our perception of other characters in the book. For the first time in this narrative, I asked myself whether Icel perceives events a certain way as he has a dislike for certain characters. So far in the series, I’ve taken that perception as truth rather than opinion. However, I’ve enjoyed questioning the validity of the narrative as presented. Outside of historical fiction, I do enjoy an unreliable narrator!
Summary
Shield of Mercia has been a fun eighth instalment to the Eagle of Mercia chronicles to read. I’ve especially enjoyed the greater action and overt conflict on this book as opposed to the political scheming of Betrayal of Mercia. That’s not to say this doesn’t underpin events in the book, because they absolutely do! However, balance has been restored, and I can’t wait to see what scrapes Icel inevitably lands himself with next…
