I was delighted to discover Lynsay Sands' Argeneau vampire series.  They're all good reads, lots of fun (if a tiny bit predictable after the third or fourth one), and I'd call them delightful brain candy.  But one would think that an author characterized as a "New York Times bestseller" would rate a bit better editor and proofreader than these books rated.  In other words, there are errors that detract from the reading experience as far as I'm concerned.  Granted, I'm a bit of a "grammar nazi," and I freely admit this.  But come on; with the price of books these days, do we as purchasers and readers not deserve better than to read offerings that include errors such as the use of "past" when the context indicates that "passed" is correct? (No, the two words are not interchangeable.)  Equally, the author's use of "he and Joe" in place of the correct "him and Joe" is disturbing.  Equally disconcerting are the number of comma errors throughout each of the books, print or electronic.  So read the books, enjoy the stories, but don't depend on them for improving your grammar.  And Lynsay, pay your proofreader better - you'll be better served.
