These are the Spanish versions of the following books published by Publicaciones Faro de Gracia:

Facing Snarls and Scowls (Brian Croft and James B. Carroll)
Mea culpa (Kyle McClellan)
Collateral Damage (James B. Carroll)

Although originally in English these books are not a series however the publisher decided to group them as such because they all have to do with the ministry of Practical Sheperding. The cover art uses photo close-ups to try to convey how immensely personal and intense the experiences described in these books are.
