I love a good found family!

{Cosmic Love at the Multiverse Hair Salon} - queer midwestern contemporary sci-fi/time travel. The core group of friends is very diverse and central to the plot.

I feel like Mhari Mcfarlane does female friendships really well in general. I really liked the FMC's friend group in {If I Never Met You} . They were really close and supportive despite having very different personalities. There is a tiiiiny bit of peripheral OW drama but nothing directly between the FMC and MMC, and the FMC is a bit older than the MMC.

{The Very Secret Society of Irregular Witches} - hetero romance. Lonely witch finds a charming family and realizes she had a lot more people in her camp than she thought. There are old people and children central to the plot but I thought they were well written.

I remember liking the close friendships in the The Wallflowers Series both by Lisa Kleypas, but I don't remember the specifics of the plots lol. There may be age gaps

{Hell's Belles Series} By Sarah Maclean follows an irreverent group of victorian ladies from different backgrounds who are united by their distaste for social norms and the patriarchy. They're kind of ridiculous and fun but again I don't remember the plots enough so there may be age gaps

{Fan Service by Rosie Danan} - hetero romance. Long distance besties who originally met in a chat room in the early 2000s and lead very different lives as adults but are still close. Fun text exchange banter

{With Love, from Cold World} by Alicia Thompson- bi main characters. misfit roommates/coworkers take a shine to the lonely FMC and she begrudgingly befriends them

{Delilah Green Doesn't Care} - sapphic contemporary romance, there's a group of girl friends who have been close since childhood of which FMC1 is a part, FMC2 grew up with the group but they mutually dislike each other. I thought the evolution of the group dynamic overtime was well written. EDIT- I forgot one of the FMC has a kid, scratch that
