Royce Buckingham, bestselling fantasy author

We used Mainwunder to launch a campaign for my urban fantasy series, Monster Lawyer. Tanja was a pleasure to work with and very responsive. She also knew the metrics for ad buys and put our advertising dollars to good use. Best of all, she was able to get my novels in front of fantasy book bloggers to amplify our advertising message specifically to readers of fantasy. As a result, Monster Lawyer has done very well and garnered hundreds of reviews. We will be back for our next campaign. Thanks Tanja!
