With all the changes taking place in the publishing industry, it seems harder than ever for even the best writers to secure a book deal. Those who do land with a traditional publisher often find that their time there is short-lived, unless their sales meet or exceed expectations. Adult genre writers are solving this problem by self-publishing, either with the help of a literary agent or on their own. But should children’s book authors do the same? I asked literary agents Kate McKean and Kevan Lyon.
