The Birth Order of Books

Most are familiar with the theory of “birth order.” Much has been written about how the order in which siblings are born has an effect on personality and development.
It got me thinking. Could the same be said for books? In particular, could this term apply to books in a series, as well?
Let’s see what is said about a first-born child. It is thought that a first-born is a leader, a perfectionist, and seeker of approval.
When I consider the first book in the Dana Greer, PI Mystery Series – Unholy Secrets – I can say with all certainty that the protagonist is all three of these. After a messy separation from her husband, resulting in a case gone cold, Dana chooses to move to a new location on an island off the coast of Maine, Cape Peril. She begins to work directly under the auspices of the Catholic Church, seeking to do her best to earn a reputation for her work. She goes about analyzing each clue to a T and seeks the advice and guidance of Sergeant Logan as she moves closer to solving the case of murdered schoolgirl Bernadette Godfrey.
Middle children tend to be more social and seek their approval from friends.
In book two – Silent Betrayal – the reader finds a social Dana Greer. When she realizes that the sergeant in the small town of Punkerton, Texas is inept, she confides with Ellie Banks, with whom she resides. Not only does Ellie provides scrumptious deserts for Dana, but the woman attempts to solve clues with Dana and introduces her to an important secondary character, Shirley Mitford. Additionally, Dana receives the attention of a handsome attorney, Howard Rhodes, who convinces her to go on a date and to travel to California in an attempt to seek out more information relative to the case of murdered prison inmate Douglas Clifford.
The baby of the family tends to be more of a risk taker.
Bitter Wrath, the third book in the Dana Greer, PI Mystery Series, certainly takes some exciting risks. One, of which, is living with an order of nuns in the Carmelite Cloistered Convent, where things are far from what one might expect for a convent. The Red Barn Tavern provides a subplot wherein Dana spies on the very customers who have no moral right to be there!
Of course, there are many variables that go into assigning traits to children, not solely dependent on the order in which they are born. So, too, with the analysis of my series, this blog was a fun attempt to describe my protagonist, Dana Greer, who, as always, will keep solving cases no matter how many books are born into the series.
