Clades on Kickstarter in October

This October, Karen and I are going to launch a Kickstarter campaign to fund our new game, Clades. Click on the card back for a quick description.

In biology, a clade is an evolutionary family. In Clades players match animal cards according to their features, including which clades the animals belong to.

Signatures for Pre-Order Customers

signatureBookplatePeople who pre-order Grandmother Fish can provide their receipts to Macmillan and get bookplates signed by Karen and me to put in their books. Karen and I asked whether we could do something special for our supporters who pre-order copies, and the Macmillan folks set this program up for us. You can order from any site and still qualify. Here’s an image of what the stickers will look like. Karen and I are going to sign each one, and some folks may get stickers or thank-yous on their bookplates, as well as signatures. The program is for customers in the US and Canada (other than Quebec and Puerto Rico).

You can pre-order from your favorite brick-and-mortar store.

We also have five online sites from which you can pre-order a copy of Grandmother Fish.

Comments Off on SOLD OUT


Ada’s Technical Books in Seattle has sold out. Folks in Australia may be able to get copies from Dymocks Camberwell, and folks in Canada might be able to find copies at the Centre for Inquiry—Canada in Toronto.

The only books I still have in stock are some of the 100 signed and numbered copies from the first edition. To help more people get these books before the holidays, I’ve dropped their price from $100 to $50. Here’s the link to the Backerkit store.

A second edition is in the works. Thanks for your interest in Grandmother Fish.

How to find Grandmother Fish

Grandmother Fish is the first book to teach evolution to preschoolers, as recently reviewed on NPR.org. We’re thrilled that our first edition has sold out on Amazon and is now available only at a few lucky stores.

  • Australia—Dymocks Camberwell
  • Canada—Centre for Inquiry Canada
  • Seattle—Ada’s Technical Books

Would you like to see your favorite bookstore on this list? We have one carton of Grandmother Fish left. If you know a bookstore that should carry Grandmother Fish, please have them contact me about ordering the last carton (contact form).

In addition, a small number of books that we had set aside are no longer spoken for, so we will release them on the Grandmother Fish store before Christmas (store). Join my email list to hear about these books when they are available (mailing list on hold).

Next we’re preparing for a second edition. Again, join the mailing list to learn more when there’s news about the second edition. (Update: the mailing list is on hold, so please Like us on Facebook to keep up with news. Thanks.)

Announcing the Clades card game!

Many fans of Grandmother Fish have asked me whether Karen and I would do another kid-friendly, science-loving project on Kickstarter, and the answer is Yes! In January, we’ll launch a Kickstarter for “Clades,” an evolution-themed card game for kids and adults. In biology, a clade is an ancestral population and all the organisms descended from it. “Mammal,” for example, is the clade of all animals descended from the earliest mammals. To write Grandmother Fish, I had to learn about clades, and the concept excited me so much that I’ve created a game based on it. For years I’ve tried to figure out how I could do a game that gets evolution right, and in August an answer finally came to me. “Clades” is a smart card with a proven play style, and it’s easy to adjust for children or beginners.

Edit: Click here for a preview of card faces, and more about the Clades game and evolution games in general.

Cetaceans will appear in the Clades card game.
