See the books!
12 months ago – Mon, Mar 13, 2023 at 03:52:38 PM

Here are the actual Acheron/Styxx Kickstarter books! Please remember that they'll be shipping to backers beginning in mid to late April and/or May. Ebooks will be emailed to backers when the books begin shipping (and those who signed on for their swag will also be sent their items when the books ship). Please be patient as Sherri will be traveling for events. She'll sign the books as fast as she can (and we'll be shipping as quickly as possible, but it will take time--several weeks-- as we are a very small staff and we have a lot of orders to fill-- thank you fans and backers).  We want to make sure every order is perfect before it leaves us. If you have any questions, please email us: [email protected]

Book Shipping Update
about 1 year ago – Thu, Feb 09, 2023 at 09:53:25 AM

We just heard from the printer and they've updated the in-hand date for Volumes 1 & 2 to April 20th. Once we receive the books, Sherri will begin signing them and we will immediately begin fulfilling orders for the books & ebooks. 

In the meantime, we will send out the Kickstarter Paladin boxes early. We are closing the fulfillment for the March Kickstarter boxes now, but if you have a last minute order you'd like to place, it's not too late. Please visit:

If you need to check on your order or update information, please visit:

Volumes 3 & 4 are on track to ship on time (barring another printing boo-boo). 

Volume 5 is still on track to ship February 2024.

All Kickstarter Paladin boxes are set to ship on time or early.

If you have any questions, the best way to reach us is through our direct email: [email protected]

In the meantime, here's a sneak peek of the Simi puzzle that will ship with the April Simi Kickstarter box:

puzzle dimensions are: 81 piece, 8" X 10"

Thanks for your patience,


Book Update
about 1 year ago – Sat, Jan 28, 2023 at 08:04:40 AM

 One other quick reminder: The ebooks will be going out with the novels. Our fulfillment tracking won't allow us to break them apart, especially given that a lot of people ordered both ebooks and regular books. We're very sorry about that, but the ebooks will be released the day we ship the first volume. If you ordered both ebooks and books, we'll send the ebook to you when we ship the regular book. Again, it's the only way to keep the orders straight and to make sure everyone gets what they ordered.

Thanks for understanding,

Jake, Kim & crew

All January boxes are shipped
about 1 year ago – Tue, Jan 17, 2023 at 11:35:27 AM

We have all the January Paladin boxes shipped out to fans. Yay!! The remainders are currently available at: 

Heads up: we are still working on the add-on items that were purchased, but they should be mailed out this week.

For those who need to check their orders, please visit: If you need to make updates or changes, please contact us at: [email protected]

Please note that not every monthly box will have a t-shirt in it. The January boxes have extra items, and no t-shirt because of that. They contain a 2023 fan club pin, magnet calendar, paper calendar, chapstick, large sparkly tote bag and a chapstick/lens cleaner clip-on). I don't know which box will have the t-shirt, but it will be one coming later in the year.

As for the books, we still don't have them in our hands. We're waiting on an update from the printer, and will let everyone know the book status once we have it. But please remember that once we get them in, Sherri will have to sign thousands and thousands of books before we can ship them out. She is standing by to do so, but these aren't like signing the tip in sheets. She's signing physical books and that will take extra time. We will start shipping them out as soon as we can.

If it looks like we're not going to get the books in time for Feb shipment, then we'll mail out the March Hellchaser boxes in Feb and the books in March. Again, we won't know that for sure until we hear back from the printer. We just want to keep everyone apprised of our plans (and backup plans). And we want to get everyone's items to them ASAP, and keep everyone informed and up to date with what's going on. 

If you have any questions, please don't post here as we don't monitor this page daily. The fastest way to reach us and get a response is to contact us at [email protected]

Happy New Year & Order Updates
about 1 year ago – Tue, Jan 03, 2023 at 11:11:18 PM

We hope everyone has had a wonderful holiday season and that the New Year brings you nothing but success and happiness!

On our end, we have most of the January boxes packed and are beginning to ship them out.

Jake wanted me to let everyone know that there are a number of Paladin boxes that are being delayed from shipping due to problems with their shipping addresses. If you've ordered the books or January Paladin boxes, please take a moment to verify that we have the correct shipping address for you.

You can check your information here:

And for those who want to place last minute orders, we still have some preorders available here:

If you have questions, please email us: [email protected] And if your question is about your shipping address and you're having trouble updating it in the system, please include the address that you're wanting to have the items shipped to so that we have the info to facilitate getting your order to you.

We want everyone to get their items as quickly as possible.

Thanks so much for your patience and participation,
