Top Ten Series I have YET To Finish

Top Ten Tuesday is hosted by the ladies over at The Broke and the Bookish. This weeks topic is ten series that are completed, but that I have yet to complete. I have a love/hate relationship with series. I love all the extra time spent with characters, but some series are just so long and drawn out. I don't even want to count the incomplete series that I have on the go that still have books to come out.

1. The Mortal Instruments by Cassandra Clare- I just need to read City of Heavenly Fire. I started this series late last year, and read the majority of them earlier this year. I was waiting for CoHF to come out in paperback, which it now has so I have no excuse.

2. The Infernal Devices by Cassandra Clare - Another reason I haven't finished TMI is because I wanted to read this series before I read CoHF. I read the first one, and didn't like it a much as the TMI books, but I do need to finish it. I've been feeling the need to finish CoHF lately, so maybe I'll finish this series soon.

3. Percy Jackson and the Olympians by Rick Riordan - I've only read the first one so far. I will eventually finish the others. I actually started listening to the second last week as I was on the treadmill, but I kind of want to just read it.

4. Anne of Green Gables by LM Montgomery - I read the first one, and I've been collecting the others in used bookshops. I bought the first and second from bookshops on Prince Edward Island, which is where the books are based.

5. Anna and the French Kiss by Stephanie Perkins -This is more of a companion series, but it counts. I've only read Anna so far. I didn't love it but I do want to continue, so I'm saving the other two for when I want a fun, quick read.

6. Lowcountry Summer series by Mary Alice Monroe - This series is about three adult half sisters who are visiting their grandmother for the summer. Each book follows a different sister. I actually don't know why I haven't finished this, as I flew through the first two.

7. Slammed by Colleen Hoover- This is one I don't think I'll actually finish. I really liked Slammed, but I don't know if I care enough to read the other two.

8. Cedar Cove series by Debbie Macomber - This series has 12 books and so far I've read 3 of them. I'm not in a huge hurry to finish these, but I will eventually.

9. The Ascendance Trilogy by Jennifer A. Nielsen - I don't actually know why I haven't finished this series because I really liked it and as they're middle grade, they're really quick reads.

I think that's all of the completed series that I haven't finished yet. There was actually more than I thought that there would be. Have you not completed any of these? Which one do I absolutely need to finish asap?
