books similar to the maddest obsession by danielle lori!!!

[mona]

so i finished the made series by danielle lori and the maddest obsession is my new favourite romance period and im looking for something to fill the void. any recommendations (doesn’t have to be mafia, can be any dark romance or romance in general) for books that have the obsession/guy is obsessed with girl (but in a mysterious way) and ideally one that spans many years or has a thick plot/backstory!!! i personally think no book boyfriend can top Christian Allister but if you read this book and you can reccomend ones that have a boy with a similar personality type to Christian please leave recommendations!!! (attentive, quiet, smart mouth, intelligent, morally grey?, sexy, and not cringe lol). also spicy reccs are always appreciated.
thx in advance 💕💕🎀
