So this book continues on from Losing It, Garrick and Bliss are engaged and are headed to London for Bliss to meet Garrick's family. Just like Losing It, Bliss is clumsy, dippy and generally really quite amusing and Garrick is as tolerant and sweet as ever. They really are an adorable couple.
While I enjoyed reading a bit more about Garrick and Bliss, and it really did make me laugh, a part of me once I'd finished was like "what was the point of this?" Especially when I'm reading away and my Kindle says 74% and suddenly Keeping Her is finished and the rest of the "book" is an excerpt from the next release Finding it (which is about Bliss' friend Kelsey). Just a little bit annoying.
I'd recommend you read this if you are a Garrick & Bliss fan and you need something to do for a couple of hours. Other than that you could safely skip it and not really be missing out on anything.
