When writing a series, the story generally changes significantly from beginning to end. I began writing the H.A.L.F. series in 2010! That's seven year's worth of life, experiences and changes in my thinking!
One of the beautiful surprises was the strength of the friendship between Erika and Ian. Their friendship was sorely tested in book two, The Makers. Book 3, ORIGINS, is no walk in the park for them either.
Will their friendship survive the trials of an alien invasion?
