I am slowly collecting the Junkyard Dog novellas into collections of three in between writing a new sci-fi series (the first book in the new series will be published in July). The second collection is now available at a discount to buying each novella separately.
Collection 2 contains Ruby City, Double Cross, and Spider Silk. Descriptions can be found on the Junkyard Dog page here.
