You can get all sorts of readings worked up for you at

They are free and highly involved. I like their different types of charts, not necessarily the generated explanations. The choice of charts is top-notch for a free site.
About Jesse, his Scorpio planets give him insight, and I think he now has Casey's number. He knows what she's capable of. He may not know first hand what she did, but his instincts are screaming on his inside. Scorpio, 8th house, secrets, things hidden.
Sometime back someone had asked about "The Encyclopedia of Astrology" by Nicholas de Vore. I have the 1947 edition in my library and I love it, although the chart of eclipses is more than 30 years outdated. The rest of the book is informative. Since I'm "old school", I like Llewellyn George's "A to Z Horoscope Maker and Delineator" (1928 edition). There are newer versions called "Llewellyn's New A to Z Horoscope Maker & Interpretor" which I also have in my library, but the old one is a classic.
