Great Gift Great Value - I had to get one for myself. The glasses are over sized and the shaker stirs up a great batch of dry Martini's. I love the retro glass look and the shaker has a seal to prevent leaking while shaking your favorite drink.

This is the story of the brother of one of the secondary characters from the Leopard Lord. Farris is sold as a slave by his stepfather. Claimed by two very different gods, his fate will be decided on what he does with his life. Will he be ruled by vengeance and violence? Or will his love of the animals he tends lead him to a different choice? Ms Morland's characterization is excellent, the plotting is much improved (from good to even better). If I had a complaint, it would be that this book did not sweep me into a different world the way that the very best speculative fiction does. However, that said, it was a most enjoyable read, and I'll buy her next book, too.

Ex Output:

I'm a huge fan of Transformers - couldn't wait for this to come out on blu-ray so I could see all the captivating colors of the autobots - as only blu-ray can! Special effects are amazing, however the story line is weak compared to the first two movies. I was a little disappointed by the story and this is my least favorite installment. Still, if you are a fan as I am, it's a must have to make the collection complete.
