The most excellent review site, Slings & Arrows has posted a nice review of book three!
“The cartooning is a delight, loose and expressive, with Fajardo really putting in the effort, regularly featuring several people per panel, and frequently as full figures. When needed, he’s great with movement, the cast having a real life to them when in action or running, and Fajardo also gives character to the pig that accompanies Beowulf.”
They have more good things to say and have given high praise to the first trilogy. The crew of Slings & Arrows knows their stuff too as they’ve reviewed over 7500 comics and graphic novels! I especially appreciate their point of view coming from Europe, since many of my own comic influences come from that tradition.
