The Sun and the Star by Rick Riordan & Mark Oshiro

Demigods Nico di Angelo and Will Solace must endure the terrors of Tartarus to rescue an old friend in this thrilling adventure co-written by New York Times #1 best-selling author Rick Riordan and award-winning author Mark Oshiro.

As the son of Hades, Nico di Angelo has been through so much, from the premature deaths of his mother and sister, to being outed against his will, to losing his friend Jason during the trials of Apollo. But there is a ray of sunshine in his life–literally: his boyfriend, Will Solace, the son of Apollo. Together the two demigods can overcome any obstacle or foe. At least, that’s been the case so far...

Now Nico is being plagued by a voice calling out to him from Tartarus, the lowest part of the Underworld. He thinks he knows who it is: a reformed Titan named Bob whom Percy and Annabeth had to leave behind when they escaped Hades’s realm. Nico’s dreams and Rachel Dare’s latest prophecy leave little doubt in Nico’s mind that Bob is in some kind of trouble. Nico has to go on this quest, whether Mr. D and Chiron like it or not. And of course Will insists on coming with. But can a being made of light survive in the darkest part of the world? and what does the prophecy mean that Nico will have to “leave something of equal value behind?”

Nico will have to face demons both internal and external as his relationship with Will is tested to the core in this standalone adventure featuring two of the most popular characters in the Percy Jackson saga.

My Review: 5/5 Stars

I feel like I have been waiting a very long time for this book and it's finally here and I could not put it down until I finished. It was absolutely amazing!! Everything you could want in a Nico and Will story. Those two have become favorite characters of mine in this world and for them to have their own story was so awesome. They are such a great pair and of course the cutest of couples. And this quest they were on tested both of them in so many ways. So for months, Nico has been hearing a voice call to him from Tartarus. And he knows it is the Titan Bob and that he needs help. And it is finally the time to act. A prophecy is received and time has run out. He must go down to the most horrific place created. Again. (We also even get some memories of his first trip there!) But he won't be alone this time. No. His boyfriend, Will Solace, child of Apollo, isn't letting Nico out of his sight. And even though he is terrified of going to Tartarus, especially being a child of the sun god, he won't leave Nico alone. Where they go, they'll go together. Together, they'll get through anything. And boy, is that put to the test. Their journey is one of the most difficult ones of the series. There are highs and lows and they'll have to find a way to not only navigate Tartarus and free Bob, but they'll have to find a way home too. I adored this story and it is one you don't want to miss. We get some great origin stories of Will and Nico and how their relationship came to be. Something I really wanted to know! Those missing details are told and so much more came along with it. We get to know them a lot better as well and things they have faced. And we get to see them grow both together and as their own persons. Nico has faced so much throughout his life and he finally gets some closure on certain things. He truly has grown up throughout this series and that becomes so clear here. And we finally get a lot more insight to Will and who he is. This was just such a wonderful story, probably my favorite of this world. And I hope this won't be the last of their adventures! Though after this quest they faced, they definitely both deserve some down time.
