I'm new to both the GLC series as well as the Tomasi/Gleason combo and was definitely entertained. I have been folling the Corp since Volume 1 and this continues the great story of them collecting the Yellow rings post Sinestro Corp War. I personally have always found Mongol a little boring even in my old Superman reading days, but they do attempt to give him more character in this collection. As opposed to other reviewers I actually really enjoyed the Mercy parts and found it a very entertaining read. I look forward to reading anything the comes from Tomasi in the future.
