May Monthly TBR & Challenge Updates

My May TBR is small because my plan is to catch up on my past TBRs and read a little more freely to prevent a slump. I was able to finish 8 books in April, which is wonderful (although literally none from my TBR). I, however, am in the middle of 7 books. I am waiting on the audio book for It at my library and I would like to pick up and finish The Cruel Prince, ACOTAR, Nevernight, Unwind, Heart of Iron, and Mr. 60%. When I'm done with some of these books, I would like to pick up some Netgalley books that are going to be published soon.

My Tentative TBR for May:

• Ace of Shades by Amanda Foody
• Harry Potter and the Chamber of Secrets (Illustrated edition) by JK Rowling 
• Brave by Svetlana Chmakova

My goal is to finish 10 series in 2018. I have a page that lists my current series: here. In April, I went through series again and decided to remove ones I was no longer interested in. My total is 40 before counting anything that I read in April.

Books read in a series this month: 1 (Obsidio)
Series finished this month: 1 (Illuminae Files) - Total for 2018: 3
Series started this month: 0 - Total for 2018: 4
Series tally: 40 + 0 - 1 = 39 series in the middle of

My goal is to read 40 books published before 2018. I don't necessarily have a list for this.
In April, I read 5 backlisted books: Pennybaker School is Headed For Disaster, Let's Pretend This Never Happened, Spellbinder, Naming the Stars, You Are Here, Fangirl. My total is now 28 backlisted books read.
