As an animal-mad kid, I {Debra Tidball} would have loved the Pet Sitters series of junior fiction books! Each book features a new adventure for friends Cassie and Lina as they pet sit a different animal each book, all with a magical twist. The constant is Gus, the mischievous and imperious cat, who can talk to the girls – but only when they are together. Some of the books are also on audio. Find out about the series here. The latest book is the newly released Pet Sitters: Billy Goat Boogie about a goat with rhythm in his hooves. It’s a really fun concept, and I’m fascinated by how Penny Reeve and Cecily Anne Paterson co-wrote the books, as Ella Shine. How did they do that?? Fortunately, Cecily is on the blog today to tell us!! Over to her:

Would you collaborate on writing a children’s book?

When Penny Reeve and I decided to write a junior fiction series together, we had no experience with collaborative writing. In fact, we both embodied those old tropes about writers: mildly introverted, needs everyone to get out of the house, cannot kill her darlings. We had no idea whether creating and wordsmithing stories as a team would be a good or terrible experience. But we shared the same strong desire – to give five to eight-year-olds excellent quality chapter books. (Also, being perfectly honest, we were probably both a bit lonely as writers and working together sounded like fun and giggles.)

The verdict
Six Pet Sitters stories and many lunches, cups of tea, and Facebook messages later, we’re glad we are co-authors. We strongly recommend collaborative writing… with some caveats.

Cherish the other person’s talents
Begin – and continue – with respect and admiration for your partner’s abilities. Not only is Penny a lyrical, beautiful creator, but she also knows so much about writing for young children. She’s fantastic at administrative detail (not my area of strength) and we connect over a slightly darkish sense of humour, which helps when we’re writing dialogue for a highly grumpy, talking cat.

Be clear about your goals
‘Let’s write books together, that would be fantastic!’ is an open-ended statement. Be more specific, and ideally, put away the wine. What type of books, and how many? Talk about the timeframe, the process and the end results. Getting on the same page right from the start is crucial. (Writer pun alert.) When you both agree, make it official with a contract or a Memorandum of Understanding.

Discover your best way to communicate
On any given day or night, I can guarantee that the Messenger chat between myself and Penny will be going strong. Some writing partnerships won’t be chatty, others will never stop. We’ve tried a few different methods of communication including emails for things we need to refer to, Slack chat, and text, but Messenger is tried and true and we always end up there. We have both learned to communicate clearly and directly without getting offended. Happily, Penny has learned to tolerate my terse answers to her questions on the days I’m at my part-time job. (Yes. Nope. Ha ha, definitely not.)

There are a million ways to write collaboratively: find your favourite.
Penny and I are both at the ‘planner’ end of the pants-plan spectrum, so we began by clearly drawing a boundary around the series and creating a firm structure for the stories. We also created detailed descriptions for our three main protagonists, the location, and some secondary characters. The story planning involves us throwing three million ideas into the ether, distilling the best ones and then creating a chapter outline. This works best if we’re face to face. The writing happens separately… but I’ll tell you about that next.

The ‘sum of the parts’, etc
One of us begins by writing the first chapter based on the story plan. She sends it to the other one, who edits the first chapter (I want to say brutally, but that sounds worse than it is) and writes the second chapter. She sends it back, and the process continues. Write, edit, write more, edit more, and so on and so forth. By the time we get to our tenth and final chapter, each person has adjusted and added to the story five times.

But we’re not finished yet. We look over it individually and send more edits. Then we meet on zoom at least twice. First, to make sure we’ve included all the series catchphrases, and to ensure our vocabulary works for the age-group. We’ll leave the story for a period, and then meet again for the second time to read aloud, adjusting for flow and rhythm.

Both Penny and I have quite different writing styles. But by the time we finish a Pet Sitters draft, the story doesn’t sound like either one of us wrote it. The combination of our creative ideas, our individual writing and our edits creates a unique ‘Ella Shine’ voice. In this collaboration, the whole really is greater than the sum of the parts.

Your turn?
Penny and I have found working together as Ella Shine on the Pet Sitters series to be a very enjoyable, creative endeavour. Have you tried writing collaborative with someone? What tips would you add to the above? We wish you as much collaborative happiness as we have had.
