Synthesis

Syl #4

by Lunadea

After surviving political chaos in the Dwarven Empire and two assassination attempts, Syl's journey takes another sharp turn. What began as a visit in stone halls among scheming nobles ended with unforeseen consequences and an unlikely friendship.

Now, Syl and Vee find themselves in the hands of the elves, far from familiar lands. Can our troublesome duo survive in these lands? Will Syl's disguise hold, or will the slimy truth need to come out? And, more importantly, what rewards are waiting around the corner?

3.5/5 rounding up

Oh no!!! KU said there were 4 books but the series isn't actually finished!!!! I hate that! I don't mind reading a series that is still in progress, but I like knowing that ahead of time!!! Ugh now I have no idea when the next book will be out?!!Lame!! But I guess that means we get more books...so it's actually a good thing, albeit annoying.

Another fun installment. We finally get some answers about the elves butttttt not much really happens. This did feel a little plot thin. Still fun tho.

I'm glad Vee became another main character. I felt like Syl kept ditching every single other person she met

Wow! I love Syl and Vee! Grab the book or start the series, to see why...

Wow! I absodamnlutely love Syl! And yeah this book was even better than the last one. OK go ahead and laugh 😃 at me, I'll wait, 'cause of the many times I've said that after finishing up another book! Sandwiched between, fighting monsters, Roll Playing dueling, and dungeon diving Syl and Vee manage to study magic, oh did you know that as bonded companions they can share spells or even borrow them if they fit their style, interesting huh. Which is just what they do, even receiving Dimension Magic. So yeah they're working hard to level up everything they can... as Syl wants to be a Riftmancer. And yes there might even be a marriage.
You're gonna hafta grab this action-driven litRPG to keep up with Syl and Vee and maybe just maybe we'll figure out what that bonus short story was all about once we have the next book in our hands!

Here's a couple of quotes that amused me:

“You are a spider!” “That doesn’t mean I automatically like them!"

“No, that’s just Syl Syl-ing,” Vee answered. “Don’t use me as a verb.”

Love this series

Spoliers ahead!
Although i was sad to see trixie leave us so soon after rejoining with her, the elves slowly grew on me. I knew Syl needed downtime to finally work on all the magic theyd learned. I do miss the days of having no responsibilities and just tinkering on spells for hours if not days on end.
The bouns chapter took me off guard and atarted reading it with "surely this is a dream, theres no way". As i continued the concept (similar to other stories id read) began growing on me and i was very ready for the beat down of that kid. Sadly it ended in a way that was not very fulfilling...
Welp, i look forward to the required beach episode next book

Ps before the bonus chapter i was very concerned about Vee exposing Syl. But as i read the bonus, pretending it was actually happening, i decided i would rather Vee expose Syl, than have to abandon 4 books of world building

My reviews are my own. If you liked this book, I’m glad you enjoyed it. If not, I respect your opinion. This is merely my opinion, so let's keep it courteous. My review is honest and voluntary.

Loved the storyline on this one, great mix of story, adventure, action, and growth. Two Issues: ONE - I had a problem with this one because of the blabbermouth, disrespectful, immature behavior from Vee. They are trying to make her sassy, but she is just blatantly rude. I hope they fix that in the next book. TWO - I also disliked the politics and how they were "resolved". Looking forward to the next book at the beach!!!

On to my next adventure, Happy Readings!!!

fun

Syl gets abducted by an Elvish butler sent by her namesake’s mother to retrieve her errant “daughter”. It’s made clear that Syl isn’t her. For political reasons the family and Syl hide the truth and have her play along as the real daughter. They lure out traitors who sought to ruin the family. Her “mother” gains power. She intimidates dungeons into helping her. And winds up engaged on paper and still the daughter of the elves. She then has to hurry to the ocean to save another Experiment (next book) and maybe have a vacation.

A fun story. The MC keeps forgetting she’s OP. The pacing if great and the narrator is Awesome. Highly recommend this series. Please enjoy

not sure if I'm getting burnout of this story but this one really felt long and dragged out. the interest in the elf kidnapping slowly waned when I realised this was going to be the majority of the book. Also, the one thing this story did NOT need was politics and the repeated attempts to force it felt unnecessary. I was also extremely disappointed in the exploration and reaction to Sly's true form. everyone seemed very happy to accept this super sentient slime and spider!?

added note: the weak and dull attempt at a cultivation spin-off (?) at the end was wildly unnecessary and pointless. I could bare get through it! I pray that this was just a 'fun' one off and not some ongoing thing...

This is a great transition point for Syl as a character. This is where she moves from a lone but powerful wanderer, who occasionally teams up with others for a time, into an overpowered major player in the world, now with a new lifelong companion in Vee. I agree with the author, Lunadea, that the Elf arc went on a bit too long, but it was still a complete and full experience. There are plenty of level-ups and evolutions, new friends, elf politics and culture, trials, and one major mystery finally resolved.

Overall, this was a very satisfying volume, even if it occasionally dragged. I’m glad to see Syl moving on to bigger and better things.

Interestingly, the best part of this book might actually be the bonus chapters at the end. Originally written as an April Fools joke that ballooned into something more, the story of Syl becoming a cultivator is a surprisingly fun clash of genres. It’s a shame it isn’t a full book on its own, but hopefully Lunadea revisits the idea in the future.

I think I'm done with the series, it was alright but got tired of the same jokes over and over; Syl seems to be OP but is constantly forced to hide her powers because #disguise; there's not much of a plot going on, it's just training and grinding levels in different settings and feels like it will be a grinding of books too.

I like the potential but it doesn't seem it will be realized. Might revisit in the future.

I continue to enjoy Syl's adventures. They are better with a companion though, so I'm glad Vee sticks around.

I have to admit though, I never considered her 'threatened' in this act of the story, so there wasn't a lot of tension in my mind, just sort of unraveling the story and building the lore and Syl's capabilities. Apparently, I'm easy to entertain.

We've seen several people worthy of knowing her secret over the course of three books, and we've been building to the reveal. So it's immensely unsatisfying when you force the reveal during an interrogation after the MC is forced to kill innocent dwarves and lose her agency, answering questions to these randos left and right despite the trust people had in her previously. Wee.

[Jim Phillips · Rating 5 out of 5]

The mini story at the end was the best!!!

Enjoyed the book, got a bit tired of the introspection but the story moved right along. Epilogue was good but the mini story at the end was the best.

Read this just for that.

[Splke · Rating 4 out of 5]

It's ok, a little less interesting then previous books. Vee started to get pretty annoying though, constantly whining about anything and everything. Complaining seems to be her main personality trait.

[Crimson · Rating 2 out of 5]

The whole elf arc was way too long and largely uneventful, we don't even get to see the actual conclusion as it's just left for the elves to deal with.

Beside one brief mention Trixie completely disappeared, the crown is also not mentioned again...

[Gabriel Morse · Rating 5 out of 5]

Next please!

Another fun story about my favorite slimy mc! Good amount of progress in this one, can't wait for the beach episode!

[Mark · Rating 3 out of 5]

Adequate for a light weight read. I'm not thrilled by the sidekick who comes from Earth, doesn't seem to add anything.

3☆

[Michael · Rating 2 out of 5]

Yeah I'm done. I'm bored with Syl as a character, the elf side story from the previous books has been paid out, and the amount of typos and weird prose make me suspect this was written with an AI tool anyway.
