Even though I really enjoyed The Unhoneymooners I haven’t picked up any other book by Christina Lauren. Also, I think I picked up the best book of theirs first so reading any of their other books is taking a step down.
It Ends With Us is fantastic and a must-read. I read Verity and Regretting You both this year. Verity was very good while Regretting You was a decent read. I’ve read most of Colleen Hoover’s books and liked November 9, Maybe Someday and Without Merit at the time I read them. Now it might be different since everyone’s taste in romance evolves with time.
I’ve heard so much about Riley Sager in the past few months that I’ve been intending to get to his books at the earliest. Now that you say he is overrated, I might read the other books I’ve been meaning to read and leave his books for later.
I haven't read any other Christina Lauren's books too though I am interested in Josh and Hazel's Guide to Not Dating and their newest, The Honey-Don't List. I am not sure when I will pick them up and like you said, many people call it their best work so I might feel let down by other books they have written due to my expectations.
Have you read You Deserve Each Other by Sarah Hogle? I read it last month and fell in love with the story. It was wonderfully written and the concept was executed so well. I highly recommend!
I am really, really interested in It Ends With Us. I have only heard praises about that book so I will be definetly picking it up soon!
Riley Sager writes mediocre book so far. I still have one book left of his which I will be picking up but I just don't seem to be impressed by how he wraps up his endings. It's very unsatisfactory.
