Judging by the history of publication dates, it will be about six months before the next book in the series is available.  (Frustrated vocalization without words.!)  No indication  from the author regarding an upcoming publication date, although she does say it is a project she is working on, but not to the exclusion of all others.

Anyway,  this is a really enjoyable storyline in which Simon and Elizabeth travel in time in order to right wrongs.  They are working from a list and so far only two names have been crossed off, so it looks as if the author is planning a long-running series, which is fine by me.  Bring 'em on, faster is better.

There is action and adventure, gun fights galore, spies and bad guys, not to mention the vampire, the ghost and the devil himself.

If I had rated each book singly, the first two books would have scored in the two- to three- star range, due to the overblown and contrived suspense factor of the budding relationship between Elizabeth and Simon.  (I love her. But I can't.  I want her. But no.  It was a mistake. But she is so desirable.) Two books of that was more than enough, but by the third one, all of that is left behind and we can get on with it already. YAY. Also there were a few Wording problems: wretch when she meant retch, placard when she meant placket, enough to divert, but not to ruination.

The period settings seem authentic, the characters are genuine, and the suspense is killing me.  MUST find out what happens next!

Out of Time Series
Monique Martin

Book 1- Out of Time ★★★★
Professor Simon Cross has spent his life searching for evidence of vampires and avoiding emotional entanglements. When a mysterious accident transports Simon and his new assistant, Elizabeth West, back in time, Simon finally finds both the proof that he's been looking for, and the romance that he hasn't. In 1920s Manhattan, they find that are more than mobsters vying for power in the city's speakeasies. Will Simon and Elizabeth's developing relationship survive the vampires' teeth? Will they survive to make it back? Or will they be forever out of time?

Book 2- When the Walls Fell (eBook) ★★★★★
Professor Simon Cross and his assistant Elizabeth West have returned from their accidental journey into the past and are adjusting to their new life together as a couple. But an unwanted visit from the Council for Temporal Studies could change everything. A murder in the past is changing the future, and if the killing isn't stopped, Simon Cross might never be born. When they arrive in 1906 San Francisco, Elizabeth and Simon have no idea who wants Victor Graham dead or how it will happen. With the earthquake that leveled most of the city just days away, the race to save Graham thrusts them into a complex mystery of jealousy and revenge where murder might be the least of their worries.

Book 3- Fragments
Professor Simon Cross and his assistant, Elizabeth West, thought their time traveling days were over. That's before they stumble across a World War II photograph -- with missing time traveler, Evan Eldridge, injured and in desperate need of help. They find Evan in 1942 London, ill and not quite sure what's happened. He remembers only one thing with crystal clarity, the whereabouts of an artifact Hitler believes can win the war. That's information every Nazi spy in the country would kill to know. As if saving Evan and surviving war-torn England weren't enough, the outcome of the war hinges on Simon and Elizabeth finding Evan's artifact before the Nazis do. But time is running out: for them, for London, for the world.

Book 4- The Devil's Due
Simon and Elizabeth's plans for their honeymoon are interrupted when they discover a list of unfinished business hidden in Simon's grandfather's journal. Picking up where Grandfather Sebastian left off, Simon and Elizabeth, along with Jack Wells, travel to glamorous 1933 Hollywood to save the life of movie star Alan Grant. But the Golden Age of Hollywood is more than parties and premieres. Behind the bright lights and bigger-than-life contracts, shadows lurk and no one is what they seem. It's a place where people will do anything for fame and fortune. And if Simon and Elizabeth fail, more than a man's life might be lost.

Book 5- Thursday's Child
The Crosses, renowned Professor of the Occult Simon and irrepressible Elizabeth, set off on their latest time traveling adventure.

Little Mary Stewart, just 8 years old, died two days ago. Mary's spirit cannot rest until Simon and Elizabeth solve the mystery of both her life and death. But Mary cannot speak, and there are those who are willing to kill to keep the past buried. Simon and Elizabeth discover first-hand that dark secrets in the Antebellum South hide pasts murkier than the river bottom and twice as dangerous.
