Now, Then and Every When by Rysa Walker

This was my W in my alphabetical list, and I guessed by the title it would be about time travel.
I wasn't wrong.

This book follows the story of Madi, who is living in her grandfather's home in the year 2136.  He was a prolific writer, though there is mystery surrounding his works as some people don't believe he actually was the author of everything he wrote, due to differing styles and topics. One day, she finds something emitting a light in the back garden - she digs it up, and it's a medallion.  She can see it is emitting a light, but other people can only see a dull piece of metal.  Madi realises this medallion is a CHRONOS key and she can use it to travel through time and space.

I'm not going to go through too much of the plot, because I don't want to give it away - not least for those of you who realise that this series is a prequel, so already know some of the characters.  I didn't realise it was a prequel, so read this in it's own right.

The blurb says:

When two time-traveling historians cross paths during one of the most tumultuous decades of the twentieth century, history goes helter-skelter. But which one broke the timeline?

In 2136 Madison Grace uncovers a key to the origins of CHRONOS, a time-travel agency with ties to her family’s mysterious past. Just as she is starting to jump through history, she returns to her timeline to find millions of lives erased—and only the people inside her house realize anything has changed.

In 2304 CHRONOS historian Tyson Reyes is assigned to observe the crucial events that played out in America’s civil rights movement. But a massive time shift occurs while he’s in 1965, and suddenly the history he sees isn’t the history he knows.

As Madi’s and Tyson’s journeys collide, they must prevent the past from being erased forever. But strange forces are at work. Are Madi and Tyson in control or merely pawns in someone else’s game?

The beginning is slightly complicated in its style, as it flips between three time zones (2100s, 2300s and the 1960s), inter-spaced between the chapters are quotes from various historical documents, which hint towards a Genetics War, a company called CHRONOS, and a "virtual reality" game called Temporal Dilemma.  However, once you get used to this, the story is really gripping. 

I loved it.  There is so much going on, and I'm sure if you were aware of the original series it would be even better, but as a standalone, it was great.  There is so much going on, and it is interesting to read about things in the past, and seeing things in the future written-as-past, as well as things in the far-future.  

In fact, my main annoyance with this book is that this series is a prequel and Book 2 of this series isn't out until JANUARY 2021!! I have already pre-ordered it, but it's ages until January!  Additionally, because I know there a series that comes after this one, I don't want to start reading those, because I'd like to finish reading the prequels, beforehand.

Gah! Life is hard when authors don't write fast enough! 😉😆
