What's the Name of That Book??? discussion

I read this book in 2016 but im not sure about when the book was published.The cover is showing 4/5 different pictures of eras if im not mistaken.The story is about a couple lives and falling in love in different time frame but the story is revolving about the friend/sibling of the couple telling this love story to their daughter.The first time frame where the hero working with this one master then fall in love with his master's daughter.The second time frame where one of them is a spy?? and the other one is a soldier in a war.The third one is in the present era where two of them are students in university.The fourth one is where they are a scientist of some important research and they are wanted because they knew some secret about the research.SPOILER AHEADDDD they are unfortunately died because of the secret they knew and they left a daughter behind.im not 100% sure of the details, im very sorry if some of them are incorrect since i read this book years ago but somehow that's what i remembered so far.the character's names are different too in their representative eras and the author also included images throughout the books such as the map where the war begun etc.the author is a woman.i really hope someone can help me to find this book since i want to read it again .

How do they get from one time frame to another? Is there a time machine (or multiple time machines) involved? Or is more along the lines of reincarnation, sort of like in "Cloud Atlas"?

i don't quite remember if there's time travel machine or not but for sure there's a few time frame involved 😄

and yeah i think it's sort of like "Cloud Atlas"

I think this might be The Next Together series by Lauren James. There’s a few books and everything you've mentioned happens across these as far as I can remember.

Good news i already found the book title within a day OMG thank you to Mrs Sarah for helping me im super grateful for it 😭 The title is The Next Together by Lauren James and the book got sequel too (i just know it LMAO gotta read the second book right away 😍)

Glad you found your book, Aina.
