The Accidental Bride (The Spinsters of Inverley #2)
Jane Walsh

Disaster looms when Lady Edith elopes with Thea’s brother. Prim-and-proper Grace and wildly outrageous Thea each wish it was anyone else by their side as they race after them to Gretna Green. In the midst of attempting to stop a wedding that will incur the wrath of both their families, they discover their passion for each other is too strong to resist.
A chance at a real relationship was the last thing either of them expected. When Grace and Thea return from Scotland, will the honeymoon be over? Or will love finally be in full bloom?
