The books I review are from a myriad of places, from review copies, gifts, bought or from the library. I always put in the top of the review under Source where they book came from.
I don't get paid to review books not do I get money if you were to purchase a book through an Amazon Link...
All of my reviews are my own personal opinions and totally honest and I will actually have read the book in question. That being said...the opinions are mine and I don't expect everyone to agree with me nor would it be a fun world to live in! Again..I don't get paid other than getting the actual book to read now and then and they do not require a positive review just an honest one!
If I do review an ARC and it hasn't been put in a giveaway and you are interested...contact me via firstname.lastname@example.org and maybe we can work out a trade! I read everything obviously!
