Lana and Xerus return…and encounter a life-altering threat.
Xerus: loyal, protective, swift, powerful. Named predomis–highest warrior among the vrisha–and guardian to his queen.
And Lana’s one true mate.
Several years after Lazris, Lana has called the vrisha’s world her home. After a long mission kept her and Xerus away, they finally return to Tryth, hoping to settle back into the life they had and spend each moment together.
But when the discovery of a galaxy-sized threat presents itself, and they learn of a dangerous empire seeking to hunt humans for its benefit, Lana and Xerus must work together to stop a major catastrophe and possible war, before it’s too late.
As large of a problem that seems, Lana finds an even darker, more disturbing, complication within her own mate. Something that could sever their relationship completely and shatter the bond they had built since the beginning.
As they strive to save the human race from being hunted and killed, Lana fights to save the one who matters to her the most.
Heart’s Keeper is the fourth book and final to the series and contains dark elements including violence and is meant for mature readers only. In order to have a complete understanding of characters and situations it is highly recommended that books 1-3 be read first in this order:
Wow. Wow. Wow. What else can I say? Heart’s Keeper was a fantastic and satisfying end to a great series.
I should firstly mention that it’s recommended to read the first three books prior to starting this one. However, I’ve only read book one (which is the same couple as this one) and absolutely loved it. I have plans to read books two and three soon but found that I was able to keep up well with this story with only knowing the characters’ names for the couples of books two and three. That being said, it did not in any way affect my review for this book and I look forward in giving this a re-read after I become better acquainted with the other couples who cameo in this book.
I don’t want to state too much about the actual storyline since I think it’ll make much more sense if you’ve read at least the first book. But what I will rave about is Olivia Riley’s writing! In short: it’s incredible. Riley creates these really detailed, complex worlds and situations, and makes it easy to follow and understand for all readers – sci-fi newbies and seasoned readers, alike. I, personally, don’t read sci-fi romance as much as I’d like and have found in the past that it takes me longer to read while I wrap my head around certain space-y elements. That is not the case with Riley’s books and instead I find myself gravitating towards trying to binge the whole book in one sitting. Both stories I’ve read by her have completely captivated my attention and left me wanting more from these alien-human relationships. And the relationships themselves… they’re a perfect balance between romance, relationship/character development, and getting things done in the plotline outside of being love interests.
Truly another fantastic book by Olivia Riley and as previously mentioned, I look forward to reading books two and three before coming back to re-read Heart’s Keeper. Heck, I might even start back from the beginning with book one and re-introduce myself to the wonderful couple that is enigmatic Xerus and kickass Lana!
