I should be rating this one higher than I am; at least 4.5 stars. I picked it up with the intention of just reading a page or two and suddenly two hours passed. I couldn't stop reading it.
But when I finished I just didn't feel that 4.5 star feeling. We can blame it on a woeful job on the part of the copy editor (lots of missing words), for lack of anything else. Because I really enjoyed the epistolary style, and I enjoyed the characters (except Soo-Lin; her, I wanted to smack and not for the obvious reasons). The writing was excellent even without the full compliment of articles and conjunctions and a lot of it was funny.
My only niggle was the ending felt abrupt; I'd have like a bit more information about what Bernadette and Elgin were going to do about those 'complications' at the end.
