Irish Chain (Benni Harper Series #2) Book

Not as good as the first, but possibly because the motive for murder was (IMHO) pretty weak. I did still enjoy the character of Benni and I like her boyfriend Ortiz, but the characters use Spanish in the weirdest way. It's almost like the author doesn't think Hispanic characters are authentic if they don't use a palabra of Spanish at least every chapter. And it is really peeving me that the story is set in "San Celina" which is obviously SLO for anyone who has lived in California for any length of time. She keeps the surrounding towns, she keeps Cal Poly, she even keeps the gum alley. Is there a rule that you have to rename the town you set your story in?
