I'm a HUGE fan of the Addicted Series, and I'm finally catching up after I somehow fell behind! I blame my classes. :P 
 Just as I have with the previous books, I loved Lily and I loved Lo, too! They're easily two of my absolute favourite book characters ever, and I think that they're completely perfect together. They complement each other so well, and I just love how they make each other stronger and that they love each other so completely. They accept absolutely everything about each other, and I love it so much! I also always enjoy their geeky comic book and fandom moments! It never fails to put a ginormous smile on my face. :D 
 I also love their friends and families! The relationships are definitely my favourite part of the series. The romantic relationships are amazing, but so are the other relationships. The sisters have such a supportive and strong bond with each other, the brothers have grown to trust and love each other so fully, and the friendships surrounding all of them are just so inspirational and wonderful! I've loved seeing them all grow so close together and I love when they work together to tackle any of their issues. It was fantastic to see Poppy and her husband, Sam, become more intertwined with the three other couples, too! I just loved that! I also loved seeing Lily connect more with her parents, and seeing Lo and his father improve their relationship, too! 
 As I've said, I LOVE THIS SERIES! It's a favourite of mine, and I think it always will be. The characters, the stories, the friendships, the romance, the families, the banter...absolutely EVERYTHING is so well done, and I'm always blown away with how much I thoroughly enjoyed all of the books in the series once I finish each one! I also just love seeing how Krista and Becca Ritchie tackle the addiction aspect in their books. We see Lily and Lo struggle with their addiction every day, but they persevere and focus on the positive parts of their lives to overcome their addictions, and it's wonderful. I also just love seeing how their friends and family support them. Alcoholism is definitely more accepted as an addiction, so Lo doesn't struggle with the image surrounding it as much, but Lily is constantly plagued by how others view her sex addiction. I've loved seeing how these stories handle her addiction, and how they work to build these addicts up instead of undermining their struggles. It's such a powerful message, and I always feel so proud of Lily and the Ritchie sisters for how the represent Lily's addiction. I love seeing how she's supported, and how strong she is in the face of the media. It's extremely inspiring, and makes me love Lily more and more! :D 
 If you haven't started this series yet, I really REALLY think that you should if it's in a genre that you like! I've loved all of the books, and I grow to love the series more and more as I read each new book, too! I'd recommend the Addicted Series and the Calloway Sister Spin-off series to contemporary romance fans, especially if you love strong characters, romances with characters that perfectly complement one another, and if you love communication, and strong character growth and progression.
