Bestselling author Allie Pleiter has published over 50 books and has sold over 1.5 million books worldwide, many of which are part of a series. Pleiter writes several inspirational romance series for Harlequin's Love Inspired imprint, and knows what it takes to keep readers coming back for more. The key to making a series successful, she says, is to have an overarching goal. In her books, Allie creates large families or communities that provide a lot of casting options. This approach creates a loyalty with readers because they are always wanting to meet more members and see how other members have fared over time. She also keeps the characters progressing, whether that's within relationships or building a family. For Pleiter, the highest compliment a reader can give is to show they care about the cast she's created.
Also when you're writing you're writing about things that a person can put you through in a relationship or a person could inspire you to write.
