Adrian Tchaikovsky's: Shadows of the Apt- Book 3; Blood of the Mantis.

And, J.R.R Tolkiens: Lord of the Rings: The Two Towers.
I only tend to read one book at a time. However, I moved house, and I lost my Shadows of the Apt book, which, I was about 3/4 through. So, my dad gave me his copy of The Lord of The Rings to read instead. I started to read that, and got completely into it. I made it to half way through The Two Towers, and then found my SotA book. So, I've been sort of trying to determine which book I want to read. However, I think I'll have to put down SotA for a while, finish The Lord of the Rings, and then restart SotA from book 3, as I've got little bits of the story mixed up.
Unfortuantely SotA book 3 is really short, far shorter than the first two, which, can only mean one thing. The story doesn't end there, and I will have to wait for the last book to come out, which is a shame, because I like being able to read the whole of a series in one go.
