It's a series about a young woman who was born into a powerful magical prophecy & a secret society was to murder her at her birth, but she was taken & given to a rich man in a different magical ability/ house/ guild who raised her to believe that she was weak in magical power, so she became a stiletto-wearing, marriage minded socialite instead. She just graduated from the academy(?), & her dream job/ life ambition is to be the magical administration building's reception hall's decorator so she can meet & marry a powerful man with the right status from an appropriate guild/family. However, her secret boyfriend/ leader of the magical world/ head of the most powerful guild (whom she’s known & flirted with forever because of her high-status parents) gives the job to her bff (whom he's dating on the side & plans to marry because she's more magically suitable), & forces her to join a rough & dangerous monster/ bad guy/ naughty troll/ misbehaving goblin- hunting task force which is lead by the brother she didn't know her boyfriend had. So she does, in her stilettos, on her own terms, & with her funny & excessively pampered cat.
I think it's 3 books.
First one they end up undercover at a hotel, & the girl works with the big hunky brother guy (who is secretly not awesome, who likes to hook up with & wreck the women on his team, I think his last team hook up was another guy on the team’s fiancée & she died... and now that guy’s not on the team), a funny, charming guy who spends more time in the bathroom & on his hair than she does, who we find out in book 2 is pure awesome, & a huge & burly animal mage guy who soothes her moody cat. She & the brother work while while the 2 funny teammates chase pretty girls at the pool in their downtime.
I think she makes herself & the brother guy disappear at the pool at one point while they amp the volume on two bad guys’ conversation.
There may have been a potty-mouthed goblin issue in book 1 or maybe 3?
2nd book she & the awesome hair guy go undercover as a married couple to a haunted, murder Inn, where the cook/maid? Is a weather mage who kills off the guests & maybe the owner too.
I read these within the last 1-3 years, I believe. It’s all starting to blur together, & I can’t remember book 3 which is why it popped up in my literary Rolodex so I can now read it again! It was hysterical & I loved it & cant remember everything anymore!!! Huzzah for the rereads! But I can’t remember the title or cover either so I can’t find it.
