I’m trying to track down a good “gospel book” for this retreat.  I have never heard of such a thing, and it seems that it is not necessarily the entire New Testament that is being asked to accompany me. 
I want a physical book. I have no issue purchasing online, but want to be careful as a quick search brings up things like evangelical gospels. 
Can someone provide a current link or safe website to peruse?  Thank you very much. 

I am going on a five day St. Ignatius retreat. Among the short list of items to bring with me are a copy of the Imitation of Jesus Christ, and a “gospel book”. The only gospel book I know of is in the New Testament. I get the feeling that this is not what is meant in that list. 
I do not know what a gospel book is, really, especially in light of bringing one to this retreat. It was suggested to me by my wife to perhaps bring Cornelius a Lapide’s commentary on the four gospels, but that is a scholarly work, four volumes, and a bit pricey (though I certainly wouldn’t mind acquiring it-seems to be a well made and well thought out collection). 
What say you? Is there something more compact and appropriate for this retreat?

Are those gospel books?

You can buy individual gospels in separate volumes with commentary.
