Nothing says awesome like a mogwai for a Christmas gift. Just don't feed it after midnight (then when the EFF are you supposed to feed it?), don't get it wet and if one has a mohawk, just throw it in a microwave now.
I don't give books star ratings; I give them bite ratings. This is a bite. A book can get up to five of these evil-looking chompers, including half bites.
You can attribute your own wording to the ratings. Five's the best, three's decent, one and under isn't worth the gas to go to the library. I'll leave it to you to fill in the blanks.
