Young Cam and Bones poster

Publishers Weekly
Adler again displays his versatility with this empathic first book in the Danny’s Doodles illustrated chapter book series. Bighearted fourth-grader Danny Cohen cheerfully plays along when new kid Calvin Waffle makes him the subject of a mysterious experiment and fills Danny’s pockets with jelly beans. Quirky and scientifically minded, Calvin wears two different socks because his right foot is “very serious,” the left “often silly,” and he answers, “Tallahassee is the capital of Florida” in response to a math problem. “I didn’t hear the question,” he explains. “And most teachers like capitals and everyone loves Florida.” Adler also tempers the story’s humor with some poignant moments: Calvin says his father is a traveling spy when he has actually abandoned the family, and the jelly bean experiment is really about making friends. Squiggly cartoon line drawings (mostly character portraits) that appear throughout are purportedly Danny’s work; they look authentically kid­like but add little to the story. The novel delivers laughs as well as a clear message about friendship and acceptance, even when one’s friend is “100% weird.” Ages 7–up. Agent: Jodi Reamer, Writers House. (Sept.)

Are Cam and Eric based on children you've known?

Cam is based on a friend of mine from elementary school. Eric is based on me.
When I wrote the first of the Cam Jansen mysteries I thought children would identify with timid Eric. I was wrong. I've been told that most children who read the books see themselves as the smart, assertive Cam.

Questions and Answers with David A. Adler, author of the Cam Jansen books

Why did you decide to write the Cam Jansen books?

I had been a math teacher in the New York City school system and was just beginning a child care leave. My first son had been born and I planned to stay home and take care of him while my wife returned to her work as a school psychologist. I had already written a few books, but I wanted to work on a series. I wanted to create a character young readers would want to read about again and again. I remembered a classmate in first and second grade with a great memory. It was rumored he had a photographic memory. The character Cam Jansen began with him. I also remembered the trouble I had when I first learned to read, the difficulty I had with the books meant to follow the Dick and Jane series. It was too big a leap for me. Even in the late 1970s, when my first son was born, there were still very few books between the easy-to-reads and the eight-to-twelves. Somehow, children were expected to make that leap. For some, it was no problem. For me and many others, it was. The Cam Jansen books (not the Young Cam Jansens) are transitional readers, books for children "in transit," from easy-to-reads to middle-grade novels.

Why did you make the Cams mysteries?

Comprehension is a real problem with beginning readers. One of my sons once asked me about a book he had just read, "What's it about?" He read every word of the book and understood none of it. He was too busy sounding out the words to pay any attention to what he was reading. Mysteries are perfect for beginning readers. In the Cams, the clues Cam remembers at the end of the books, the clues that solve the mysteries, are there for the reader, too. Cam's readers, hopefully, are alert. They try to find the clues and solve the mystery before Cam does.

What makes Cams transtional readers?

The Cams are not simply chapter books with easy reading levels. Children who are just begining to read on their own, read slowly. They read every word. But they don't think slowly. We can't ask them to speed up their reading, so to keep their attention it's necessary to keep the story moving. The Cams move quickly. Something is always happening. Characters are introduced through dialogue and plot. Scenes are set in just a few words.

Why did you decide to make Cam a girl?

I like to write against stereotypes. Cam, as a girl, is curious and assertive, just as many girls really are. But that's not their stereotype. It's my hope that the current generation of readers will be open to treat people as individuals, whatever their gender, race, religion, or age.

Did your years as a math teacher influence your writing in any way?

I approach my Cam Jansen mysteries as math problems. First I set up the problem -- to create a mystery that will be solved with visual clues. Then I go about solving it.


Cam Jansen and Young Cam Jansen Mysteries

If writing is like swimming... An interview with Bruce Black:

1) how do you get into the water each day?
The only way to get into the water is to jump in. Don't over think the process. Just jump in and write.

2) What keeps you afloat...for short work? For longer work?
I keep rereading what I've written and that takes me deeper and deeper into my story.

3) How do you keep swimming through dry spells?
How can there be dry spells in swimming? Being dry can only mean you stepped out of the water. If I get stuck working on one manuscript, I start or continue work on another. I find it helpful to work on more than one project at a time.

4) What's the hardest part of swimming?
The hardest part, I find, is discovering the voice for my story and that comes at the very beginning.

5) How do you overcome obstacles, problems, when swimming alone?
Writers always swim alone. I try not to put too much pressure on myself, not to demand a great first draft. But I keep rereading and rewriting until I'm satisfied.

6) What's the part of swimming that you love the most?
It's the swim I love, not the jumping in the water, and not the stepping out. I love the rewriting, just playing with my words. I feel somewhat sad to finish the final rewrite and have to send off a cherished manuscript.
