Do you love series books? For me series books are like a drug of choice to an addict - I’m drawn into their spell and can’t get out. Maybe series books are a ploy by authors to get me hooked on their dastardly drug; every time a new book is released I tell myself not to fall for it, this subtle manipulation that spells my downfall, 
because once I start reading the latest book I don’t want to leave the house or even eat. I HAVE to know how it ends as soon as possible. It’s as if I can no longer control my life that is being taken over either by aliens, hot detectives or rock stars. Has this happened to you?
I follow several series and they are all exceptionally well written.Some of my top favourites are PsyCop by Jordan Castillo Price, Cut & Run by Urban & Roux (now only Abigail Roux), The Draegan Lords by M.L. Rhodes (I wish she would release the next instalment of this series which is long overdue), 
With 
and Without by J.L. Langley, Sci Regency by J.L. Langley, Dangerous Ground by Josh Lanyon, I Spy by Josh Lanyon, Holmes and Moriarity by Josh Lanyon, Channeling Morpheus/Sweet Oblivion by Jordan Castillo Price, Deputy Joe by James Buchanan, The Administration by Manna Francis, Bay City Paranormal Investigations by Ally Blue, Coda by Marie Sexton, Deadly by Victor J. Banis, and Deviations by Chris Owen and Jodi Payne. A few of my series have ended: Adrien English Mysteries by Josh Lanyon, Heaven Sent by Jet Mykles, Channeling Morpheus/Sweet Oblivion by Jordan Castillo Price and Petit Morts by Jordan Castillo Price, Josh Lanyon, Sean Kennedy & Clare London. I can read them over and over again and there are no more surprises, which is a good or bad thing depending on your perspective. 
At least there is no cliffhanger to piss me off because I know how the stories end. 
What is it about series books that have us so enamored? Is it the writing? The characters? The plots? The worlds the authors create? For me it’s all of the above and my favourite series fall into a mixed bag – from BDSM to horror to mysteries to contemporaries to science fiction and paranormals.
On the other side of the coin:
Have you ever started a series which you really liked and then discovered that later books changed the direction and the overall story arc? If this happened to you what did you do? Years ago I followed a vampire series. To my shock, when book 3 was released there was a new love interest for the MCs and a twosome became a threesome. I had thought that the MCs were happy in love and devoted to each other, and I became invested in them, but when the story arc and plot changed with the addition of a new MC I was devastated and immediately stopped reading the books.
Like many of you I wait impatiently for the next book(s) in my series, sometimes for 18 months or even longer. Occasionally, when a new book is released the story arc has changed so much I’m disappointed, in which case I usually move on and never read 
the series again because for me one of the best attributes of a series is that the original story arc is consistent despite new plots/adventures and the evolution of the series. Most important to me, the MCs must remain faithful to each other (outside of really exceptional circumstances), and in love throughout the course of the series because I don’t want to read about my heroes messing around with a new love. Can you imagine Victor and Jacob from PsyCop or Ty and Zane from Cut & Run with new love interests? 
What are some of your favourite series and what is it about them that fascinates you? Do you sometimes get mad if there’s a change in the story arc or a cliffhanger at the end of the latest book? Do you wish that certain authors had ended their series a few books ago because they have exhausted the plot and story arc and seem to be driven solely by making more money? Why do you love series? What would turn you off one of your favourites?
